Bio 405 Genetics Mendelian Inheritance This video is talking about the Mendelian genetics. This videos starts off by telling us the meaning of both genetics and heredity. Genetics can be used in many different subjects such as zoology, molecular biology, microbiology and topics dealing life as examples. It then goes on to discuss the father of genetics which is Gregor Mendel who was and Austrian monk that grew up with a family of religious beliefs. Throughout his life Gregor was interested

Is genetic engineering ethically right? Genetic engineering was first discovered in the 1970’s and since then ethical questions been raised regarding the process and results. Some people are excited by the possibilities of genetic engineering while others believe the process is unethical and should be banned as they claim scientists are ‘playing god’. Ethics is the philosophical study of what is morally right or wrong. It is a system of moral principles. They affect how people make decisions and

to carry oxygen to all parts of the body, and carbon dioxide to the lungs to be exhaled. The following essay will be discussing Thalassemia and the results of genetic testing. This disorder is passed on through genes and it is vital to understand how this disease can affect the future generations of families. It is caused by either a genetic mutation, or a deletion of certain key genes. T t T TT Tt t Tt tt The two types of Thalassemia are Thalassemia Major and Thalassemia Minor. Thalassemia Major

with the US Patent Office alone, and many more abroad. “ (http://www.disabled-world.com/fitness/gm-foods.php) The first food that was ever grown as a GM food was a tomato and was discharged into the market in 1994. Dr. Mae-Wan Ho states that, "Genetic engineering is inherently dangerous, because it greatly expands the scope for horizontal gene transfer and recombination, precisely the processes that create new viruses and bacteria that cause disease epidemics, and trigger cancer in

cell. Plasmid is a DNA molecule. Flagellum is a “tail” that wipes back and forth allowing the cell to move. Plasmid is found in bacteria. They need a host to live of. It is a clone of the bacteria’s DNA. It typically provided the bacteria with genetic advantages, such as antibiotic resistance. Plasmid can be passed to other cells through a process called conjugation. Plasmid can be cloned into daughter cells thousands of times, making it easy to spread the bacteria’s DNA. Plasmid is not said to

For something to be consider alive it must meet all nine of the properties of life. The first property of life is order. Order is when each structure or activity lies in a specific relationship with all other structures and activities (Hopson, 2011). The next property is metabolism; this is when an organized chemical breaks down molecules to make energy and needed parts (Hopson, 2011). Motility is the third property; it allows the organism to move themselves or their body parts. Responsiveness allows

Mendel’s principle of inheritance Principle of segregation Two alleles per offspring, one from each parent Independent assortment Distribution of one pair of alleles does not influence another pair Genes don’t blend Eukaryotic and prokaryotic Prokaryotic – are one celled organisms. Two kinds- bacteria and archaea Cells structure is simple Eukaryotes- every organism that has more than one cell. Cell structure is more complex than prokaryotes Prokaryotes Prokaryotic cells are one celled

it carries a unique code that makes us who we are. These codes are passed down from one generation to the other, and over a period of time, contribute to evolution. Behavioral Genetics is the study that explores the genetic and environmental roots of human differences. Myers (2014) Simply put, it is the study of how genetics affect our behavior. Behavioral geneticists explain these differences by studying identical twins, fraternal twins and adopted children. I found the study involving the twins

Kimmelman Jonathan, Baylois Francois, Grass Kathleen, (2006) “Stem cell trials: Lessons from gene transfer research”, 23-26. When I first heard of stem cell research I wondered how the government could refuse Stem cell research, something that holds the cure for diseases like Alzheimer’s , Cancer or even HIV/AIDS. I didn’t know the background story and how stem cell research borders on the morality of what is ethical and what isn’t. Is it acceptable to save one life but kill another? The

Genetic Factors are those that we inherit through our parents, they are used to explain why aggression runs through families. Genetic factors play a role in aggressive behaviour and lies within an individual’s genetic make-up. Psychologists, look at twin studies to try and find evidence on a genetic basis to compare the degree of similarity of aggression between sets of monozygotic (MZ) twins and dizygotic (DZ) twins. A lot of the time, it is found that aggressive behaviour is more highly correlated
