Why are only inherited variations important in the evolutionary process? Explain your answer.
The dog breed West Highland Terrier is a product of artificial selection. Give a brief description of the breed and its desired traits. What wild ancestor did it come from? Was it produced with selective breeding or genetic engineering (i.e. genetically modified)? What are the benefits of artificial selection in this case? Are there potential negative consequences?
A common misconception of evolution is that it should naturally eliminate "harmful" alleles/mutations if they do not assist survival or reproduction. Explain why this is inaccurate and how these "harmful" mendelian alleles persist within the human genome. In your response, give an example of a mendelian allele that causes a "harmful" genetic disease that does not appear to have a beneficial component

- What is the role of variation in evolution – if heterozygosity is reduced, what happens to the potential for evolution?arrow_forwardExplain how it is that natural selection doesn't act on genes?arrow_forwardIn your group, consider the following statement: "Mutations are random, natural selection is not." What does that statement mean?arrow_forward
- How does genetic information provides evidence for evolution? (With species as example)arrow_forwardDo you think the human race is continuing to evolve in a Darwinian, genetic sense? Are the genes of our species changing? Do not just write "yes" or "no," but explain why you think so. In addition, include in your explanation of how the mechanisms of evolution, such as natural selection, would be at play.arrow_forwardIf heterozygosity is reduced, what happens to the potential for Evolution?.

- In your own words, explain the factors that lead to the Phenotypic variation and its importance to evolution.arrow_forward"evolution is an integrated process" and uses sickle-cell allele as an example. In just 2-3 sentences, trace the various factors that influence evolution based on this example. I just want to know how Darwin, Mendel, gene flow, genetic drift, mutation, recombination and even the environment serve to create evolution. Thank you.arrow_forwardIn your own words, explain the difference between ancestral and derived traits.arrow_forward
- Why are model organisms so useful in genetics research? Choose one model organism and explain an experiment that taught us about human genetics. Why was that organism a good choice for the experiment?arrow_forwardProvide 3 reasons why natural selection allows only the better alleles to be passed onto the next generation. Please explain in details.arrow_forwardHow is evolution through random processes different than evolution through natural selection?arrow_forward
