1. What 2 factors are most commonly responsible for decreases in genetic variation? 2. What effect would increasing gene flow between 2 populations have on their gene pools? 3. New genetic information (alleles) can be introduced into a population through what mechanisms? 4. A population of what kind of organism would most closely resemble an equilibrium population that is not evolving? Explain why you think so (Hardy- Weinberg conditions).

Step 1
The two factors that are most commonly responsible for decreases in genetic variation are genetic drift and natural selection. Genetic drift is the random fluctuation of allele frequencies in a population, which can lead to the loss of alleles over time. Natural Show more…

1. What causes variation in the phenotypes in offspring? 2. How does phenotypic variation influence the survival of offspring? 3. How do reproduction rates differ between offspring with favorable vs. unfavorable traits? 4. How can different reproductive rates change the characteristics of a population over time? With examples, and the most important question for me from all of them is question 4?
