How would the gene flow or genetic drift affect the population in which either of them happen to take place ?

Text Solution

Verified by Experts

Hardy-Weinberg principle states that the gene pool (total genes and their alleles in a population) remain constant.
Gene flow, Genetic drift, mutation and natural selection affect the Hardy-Weinberg equilibrium. Gene flow is the transfer of genetic variation from one population to another.

Fill up the balnks in the following paragraph by selecting the correct option. When migration of a section of population to another place and population occurs, I change in the original as well as in the new population new genes/ alleles are added to the ii, population and these are lost from the population. These would be a iv if this gene migration, happens multiple times. if the same change occurs by chance, it is called v. sometimes the change in allele frequency is so different in the new sample of population that they become a diffrent species. The original drifted population becomes founders and the effect is called vi
