Genetic variation is evident. The variation in your community is simple evidence of understanding the basics of evolution. How does this imply the existence of evolution? Does this mean that some humans are
more evolved than others?
25. Answer the following questions based on the facts and inferences related to natural selection that we discussed in class, as well as the simulations you performed with the Evodots lab. If individuals vary, and variation affects survival and reproduction, and variation is heritable:
there will be natural selection resulting in evolution.
there will be no natural selection, but there will be evolution due to natural selection.
there will be natural selection, but it will not result in evolution.
there will be no natural selection, and there will be no evolution due to natural selection.
24. Answer the following questions based on the facts and inferences related to natural selection that we discussed in class, as well as the simulations you performed with the Evodots lab. If individuals vary, and variation affects survival and reproduction, but variation is not heritable:

Using the concepts of variability, environmental pressure and natural selection how does the synthetic theory explain the darwinian natural selection?

- Natural Selection Affects the Frequency of Genetic Disorders Will a recessive allele that is lethal in the homozygous condition ever be completely removed from a large population by natural selection?arrow_forwardIn a small group of people living in a remote area, there is a high incidence of "blue skin", a condition that results from a variation in the structure of hemoglobin. All of the "blue-skinned" residents can trace their ancestry to one couple, who were among the original settlers of this region.

Thanks for your help.arrow_forwardWhat is the role of variation in evolution If heterozygosity is reduced what happens to the potential for evolution?

- Part 1: Define natural selection. In your definition, be sure to explain whether selection acts on traits or genotypes, and what genomic patterns indicate selection has taken place at a locus.
