...April 30, 2012 Genetics Angus Heifer 293 Angus Heifer 293 is a of S A V Final Answer daughter and has very high genetic value in most economically profitable traits such as tenderness, average daily gain, marbling, percent choice, yield grade, and heifer pregnancy. These traits in my opinion classify this heifer as a replacement heifer due to the valuable industrial traits she posses which are highly heritable to the next generation. By breeding this heifer to a sire which excels in CEM, rib eye area, and heifer pregnancy will provide a next generation calf will have a greater chance genetically for the deficient traits of this heifer. Some disadvantages of this heifer’s genetics are the low rib eye area When I was selecting a sire for this heifer I took into account SAV Final Answer‘s EPD information and family lineage to ensure that there is no chance of accidental inbreeding with the intended heifer and potential sire. SAV Final Answer excels in many economically important traits along with reproductive efficiency. He has excellent production traits such as +12 CED, -1.0 BW, +61 WW, and +14 Docility; along with production traits he also excels in maternal, carcass, and $value traits for example the maternal calving ease is +13 above industry average and a heifer pregnancy rate. Due to the inheritance factor there is chance that future offspring will inherit some of the traits. I have chosen Select Sires GAR Ingenuity 7AN341 as the sire due to the high rib eye...

...ORIGINAL REPORTS: CANCER INTEREST, AWARENESS, AND PERCEPTIONS OF GENETIC TESTING AMONG HISPANIC FAMILY MEMBERS OF BREAST CANCER SURVIVORS Objective: To provide a preliminary description of the interest, awareness, and perceptions of genetic testing among Hispanics with a family history of breast cancer Design: This cross-sectional pilot study used interpersonal structured interviews for data collection. Participants: We interviewed 48 Hispanics without breast cancer but who had a family member with breast cancer; participants lived in San Antonio and the surrounding area. Main Outcome: The outcomes were interest in breast cancer genetic testing, awareness about genetic testing, perceived risk of carrying a breast cancer susceptibility gene, and the perceived benefits and risks associated with a genetic test. Measures: Items previously used in research regarding interest and perceived genetic risk and a previously validated benefits and riskslimitations scale for genetic testing commonly used by other researchers were used to measure the outcomes. Results: Awareness of genetic testing for breast cancer susceptibility was very low, yet most (82%) participants were interested in a genetic test for breast cancer susceptibility. Participants were more likely to identify with the benefits than the potential risks of genetic testing. The most highly endorsed benefits were to know to take better care of one’s self and to undergo more frequent screening. Conclusions: Hispanics seem to...

...Introduction Introduction Outline and evaluate the role of genetic factors in aggressive behaviour (5+16 marks) Moghaddom (1998) distinguishes between explanations of aggression which are normative, and those which are causal. Causal explanations, as in this case, suggest aggression is determined by particular factors e.g. genes and are usually biological explanations. The genetic explanation of aggression suggests that it is influenced through our genes, and that such behaviour is therefore inherited. Para 1 A01 Para 1 A01 It is thought that aggression is due to a defective gene that is inherited by following generations. One possible gene is the Monoamine Oxidase A gene, which produces Monoamine Oxidase A enzyme that breaks down neurotransmitters associated with aggression. It is thought that a build-up of serotonin and dopamine can cause an individual to act aggressively to stress in the fight or flight response. There are two forms of the gene, MAOA-H (produces a high level of the enzyme) and MAOA-L (produces a low amount of the enzyme). The presence of the MAOA-L gene is related to an increase likelihood of aggression. One third of people in Western countries have the MAOA-L gene, compared to two thirds in countries with a history of warfare; leading the gene to be dubbed with the term “warrior gene”. Para 2 A02 Para 2 A02 Research to support the role of the MAOA gene comes from Cases et al who disabled the gene in the X chromosome of mice. As no enzyme was produced...

...Checkpoint: Heredity and Hormones Elizabeth L. Saylor BEH 225 November 3, 2011 Axia University of Phoenix Checkpoint: Heredity and Hormones Heredity and hormones can make or break a person. To compare and contrast the influence of heredity and hormones on human behavior we must first understand what each is and what role it plays. Hormones are chemical substance that is released into the bloodstream to guide the processes of sexual development, metabolism, and growth (Morris & Maisto, 2005). Hormones have different effects on the different genders. With women hormones cause mood swings, people always assume that when a female in menstruating she is automatically in a bad mood that is not the case what happens are the women’s hormones are out of balance and this causes the “mood swings”. Thank goodness there are medications both over the counter and Doctor prescribed to help balance out the hormones. Hormones organize the entire nervous system during puberty. Hormones are responsible for behaviors because they affect alertness, excitability, sexual behavior, concentration, aggressiveness, and how one reacts to stress (Morris & Maisto, 2005). The hormones estrogen and androgen cause acne flare-ups when they are out of balance. The endocrine glands are the main glands that regulate our hormones. Endocrine glands are pituitary gland, gonads, thyroid gland, and the pineal gland (Morris & Maisto, 2005). Heredity is when genes and personal traits are passed...

...Describe and evaluate the social learning theory approach in psychology. The social learning theory approach argues that it is the mediational processes which lie between the stimulus and response, influence our behaviour and the way we act. This is when we witness a certain action and then thought processes occur, this is where we consider how we behave. For example, a child may be watching the tweenies’ and witness reinforcement for good behaviour, they then would like the same reinforcement and therefore imitate this good behaviour. Another assumption of the social learning theory is that learning can occur by observation of others, such as role models. Social learning psychologists argue that we are more likely to imitate people who are similar to us, people in high status and people who are of the same gender and are warm, supportive people. An example, many young boys may imitate David Beckham by playing football and dressing the way he does, this is because of his high status. The social learning theory also believes can be a result of direct reinforcement and indirect of various reinforcement. An example of this is a child observing another child being rewarded for a behaviour and then decides to imitate this behaviour. Indirect reinforcement is when a child in the audience watches a child receive a medal for winning in a match the child in the audience watches this and wants to do the same. ‘modelling’ is when someone is modelling out behaviour with no intention...

...Creationism VS. Evolution “Why evolution should be taught in public schools” by Laura H. Kahn discusses how evolution being taught in the public school system is essential to our future in science and medicine. Kahn discusses how the theory of evolution has come to be over the many years of research and experimentation by many famous scientists, she also talks about the uphill battle it has been for the theory of evolution to be taught in the public school system because “certain segments of society insist that religious doctrine, masquerading as science, be taught instead. Laura presents her audience with the facts that in the nineteenth century theory of spontaneous generation, the theory that proposed that life could emerge from nonliving material, was the main theory of evolution back then. How ever a French chemist, Louis Pasteur, would try to disprove the theory through his discovery that yeasts were responsible for making wine palatable and bacteria was responsible for turning wine bad. He also discovered through the use of silkworms that microbes caused their illness and death. She states that Pasteur saw the connection between microbes, fermentation, putrefaction, and disease. She claims that his biggest challenge however was to try to convince the scientific community to accept is idea. She backs up her statement with bringing to our attention that at the same time Pasteur was pushing his theory a scientist by the name of Felix-Archimede claimed he had successfully...

...nothing. We have to find new and better ways to produce food. We cannot just search for short term benefit and not research what the future may bring. Genetically engineered food could give people enough food to eat but does come at too high a cost. Genetic Engineering of Food is not the way to cure world hunger but it is a way to stop or slow the growth of hunger. The question must be answered on several different levels. We see that the yeilds of the genetically engineered food is higher but at what cost. The cost of feeding people today could mean starving people tomorrow or worse contaminating them. Genetically engineered food yeild more crops but we must examine how it is done. The plant crops are resistant to insects. Through gentic means these crops are either unappealing to insects or at worse poison to them. Making it unappealing means these insects have to find alternative foods. This could mean that they will devestate other products and start a change in the way ecosystem. Poisoning the insect would cause a similar change. We have to consider that these insect maybe the food source for other insects and birds. What happens when they must seek new food sources? What happens when these insects are...

...Hearing in Infants Ages Birth to 12 Months: Child Growth and Development Tamesha Robinson Collin College Child Growth and Development TECA 1354 Professor Susy A Mathews Associate Faculty Office SCC B-103 or Child Development Lab School Spring Creek Campus Development of Hearing in the Womb Infants sense of hearing under goes most of its development in the womb (Baby center) states that a baby’s inner ear fully develops by the 20th week of pregnancy. The ability to hear is fully developed at birth. While in the womb, babies can hear your heart beat, your stomach grumbling and the blood moving through the umbilical cord. Babies are even startled by loud noises. The results suggest newborns will gravitate toward and pay more attention to what may be “their mothers melodic sounds than those of other women, and will pay more attention to other similar sounds like female voices in general, than they will to even less similar sounds, like male voices. The findings add to evidence suggesting that prenatal hearing can help infants perceive the sounds of speech. It was long know that newborns can discriminate or perceive most of the acoustic properties of speech. The theoretical view is that these capacities are mostly independent of previous auditory experience and that newborns have a bias or skill for perceiving speech. Scientist...

...Patrick Zimmer Home | Projects | Music | Sitemap | Contact Genetic Engineering Essay Projects / Academic / Genetic Engineering Essay GENETIC ENGINEERING - The benefits and problems Genetic engineering is a powerful and potentially very dangerous tool. To alter the sequence of nucleotides of the DNA that code for the structure of a complex living organism, can have extremely ill effects although the potential benefits can be huge. Before advances in genetic applications, gene therapy was unheard of and genetic defects were always inherited, plaguing generations. Today genetic testing is widely available, such as prenatal karyotyping of chromosomes to check for genetic abnormalities. Genetic testing is also useful for families in which autosomal recessive disorders are known to exist, when these are planning to have children. In addition, genetic testing is available for people who might have inherited a genetic disorder which only becomes apparent later in life (for example Huntington's Disease). Individual choice decides whether a person would rather know if they are particularly vulnerable to certain diseases or more likely to die young. Knowing that your life may be short could inspire you to make the most of it while it could equally well cause severe depression. Today`s advances in gene therapy make it possible to even remove a faulty gene and replace it with a functioning gene in cells lacking this function. Though these techniques are available, they are still in...

...Is genetic engineering the answer to ending global hunger? Jennifer E. Law SCI 207 Haleh Keshtkar February 27, 2012 The controversial statement that genetic engineered food may be the solution to hunger in the world is gaining more and more interest by the media in today’s society. On the one hand, supporters of biotechnology believe that genetic engineered food ensures and sustains food security around the world as the population increases, but on the other hand, there are many concerns involved with genetically modified food. In fact, a lot of food that we eat on a daily basis contains genetically modified ingredients and usually without our knowledge. Yet, is genetic engineered food safe? Moreover, do we really need genetic modified food? Many researchers do not consider biotechnology the solution to hunger but they believe that poverty is the cause of famine in numerous countries. As a result, biotechnology raises various questions among citizens and farmers since there is the assumption that genetic engineered food is the key to eliminating global starvation (Genetically, 2010). Before weighing the pros and cons of genetic engineered food, it is essential to understand what is genetic engineered food? “Genetic engineering is a laboratory technique used by scientists to change the DNA of living organisms” (What is genetically, 2010). Scientists have learned that there are ways of changing the structure of DNA in living organisms and build customized DNA. Genetic...

...Abstract There are four types of lupus, systemic lupus erythematous, discoid, drug-induced, and neonatal lupus. Systemic lupus erythematous, also known as SLE or lupus and is sometimes called the “great imitator” due to the fact that it mnemonics so many other diseases. Family practice offices often misdiagnose lupus due to lack of symptoms at the time of visit, patients being poor historians and lab work that is inconclusive at that time. Discoid lupus affects only the skin and causes rashes and lesions mostly of the face, neck and scalp. During drug-induced lupus the person will experience lupus like symptoms. These symptoms usually resolve within six months after the drug is stopped. Individuals with drug- induced lupus may have a positive Antinuclear Antibody test more years after the episode. Neonatal lupus occurs when a child is born to a women with lupus. The infant may have lupus symptoms including rashes, anemia and liver problem which usually resolve within a few months. Some infants born to mothers with lupus may have serious heart defects. For the purpose of this paper the focus will be on systemic lupus erythematous. Systemic Lupus Erythematous Systemic lupus erythematous is a complex multisystem autoimmune disease in which the body’s immune system misfires and makes autoantibodies that attacks its own tissue. Lupus affects as many as 1.5 million people in America. (U.S. Department of Health and Human Services, 2007) Women are more commonly affected...
