How did the following historical events defy the condition of Hardy-Weinberg equilibrium: a. homo erectus migration for Africa to Asia b. The pilgrims and the Mayflower c. The Holocaust d. Hungary physically closing its border with neighboring SerbiaExplanation / Answer
1) Migration in population genetics is also known as gene flow. It can have two impacts on the population. The genetic divergence between the populations, interacting by migration, is reduced. Secondly, the genetic variability within the population is increased.
2) a) Hardy-Weinberg equilibrium believed that there is little or no effect of migration between populations but Homo erectus migration significantly affected the gene pool.
b) by Migration to an isolated population, HWE is violated.
c) artificial selection of traits by large killings of Jewish people and non-random mating.
d) Changed allele frequency by reducing a very large population into two large populations.
