Genetic Diversity Issues Genetic diversity can be seen everywhere we look. These differences give us variety whether we are talking about humans, animals, insects, or plants. These same differences can cause issues over time, however. When we discuss genetic diversity it involves mutations, sexual reproduction, migration, and population size. All four of these factors add to the variety we see every day and are deeply intertwined and can be problematic.

Kaylee Thelen Genetic Diversity Generally speaking, there are numerous issues related to genetic diversity which include mutations, sexual reproduction, migration, and population size. Genetic diversity, or the level of biodiversity, refers to the total number of genetic characteristics in the genetic makeup of a species. Biodiversity is the degree of variation of life forms within a given ecosystem, biome, or an entire planet. To begin, a mutation is a permanent change in the DNA sequence

to have access for genetic information, who owns the privacy and the confidentiality of this genetic information, the reproductive, clinical, health and environmental issues. The National Institutes of Health and U.S. Department of Energy has dedicated between 3-5% of the annual budgets to study the ethical, legal and social issues that surrounded the availability information for genetics. When it comes to gene patenting inventors have to follow; identify the novel genetic

approach suggests that psychological disorders should be treated medically, as this model puts forward the idea that any psychological abnormality is causes by genetic factors and body malfunctions. The model as 4 different elements that may be the cause of psychological abnormalities; viral infections, biochemistry, brain damage, genetic factors. Several studies have been carried out by different researchers to investigate the theories of the model. Biochemical elements, is one of the highly researched

Genetics H e a l t h f o r l i f e 1. What are Genes? What roles do they play? Genes give the directions for building protein that make our bodies function. They give instructions on how to make or operate all parts of out body. 2. Describe what dominant and regressive genes are. Give some examples. Dominant Gene- A gene which, when present on a chromos ome, passes on a certain physical characteristic, even when the gene is present in only one copy. Recessive Gene- A gene which must

How Genetics Influence Down Syndrome PSY 104 Professor Vincent July 7, 2013 How Genetics Influence Down Syndrome Genetics play such an vital role in our development. Every individual carries genes from their mother and their father. Characteristics such as height, eye color, if we have curly or straight hair are all determined through the our genes and specifically our chromosomes. Many times, parents inadvertently pass genes on to their children through their DNA that may contribute to developmental

essentially as a result of the four processes which in this case are mutation, gene flow, genetic drift, and selection both artificial and natural. Mutation is actually a nucleotide sequence change of an organism genome, extra chromosomal genetic element, or virus. These processes come as a result of unrepaired damage to the RNA genomes or to DNA, the deletion or insertion of DNA segments by the mobile genetic elements, or from the errors that result from replication process. Mutations therefore

a means of survival. It is necessary in order for a species, like the human race, to reproduce and therefore will always be a topic of thought and discussion. The need and use of sex both in and out of marriage is determined and manipulated by genetic code. Genes have a way of working to either sabotage or safe-guard a relationship. Infidelity Marriage and sex go hand-in-hand and unfortunately infidelity often is part of that union. Both men and women cheat, but for very different reasons.

lasting and debilitating. It may intensify as the months go by. People with clinical depression may become unable to carry out the simplest of life’s activities, and some even try to end their lives. Biological theory researchers have relied on genetic studies and on investigations into biochemistry to help explain the causes of unipolar depression. Many theorists believe that some people inherit a predisposition to unipolar depression. Support comes from many sources – family studies, twin studies

results in greater degree of variation. Two parents give rise to offspring that have unique combinations of genes inherited from two parents. Sexual reproduction generates genetic variation by homologous parings (half of the chromosomes form the mother and half from the father). The process crossing over is the exchange of genetic material which enhances variation in a species; it produces recombinant chromosomes, which combine genes inherited from two parents. Crossing over occurs early in meiosis
