In a large, sexually reproducing population with random mating with respect to phenotype, the frequency of an allele changes from 20% to 60% across several generations. Based upon this change in allele frequency, the most likely cause of the change is that the allele mutates readily. that genetic drift is responsible for the increase in the allele’s frequency. that the allele codes for a trait that is maladaptive in thepopulation. that the allele codes for a trait that is adaptive in thepopulation.

Allele frequencies in a population are considered to be stable over a period of time, unless countered by other processes such as migration, which in an evolutionary sense refers to gene flow across populations, or mutations. Migration leads to mixing of genes between populations and is likely to affect the distribution of allele frequencies in populations. How does it affect the allele frequencies across populations? What would be the effect of a small population receiving immigrants from a large source population?
