Question
Two populations of antelope are separated by a mountain range. It is known that the antelope may occasionally migrate from one population to the other. Migration can occur in either direction. Choose all the answers that best describe possible effects of migration.

Allele frequencies will remain similar between these populations. Genetic diversity within each population will remain lower than a situation without migration. Genetic diversity within each population will remain relatively high compared to a situation without migration. Genetic variation between the populations will be very high. Allele frequencies will diverge between these populations. Homozygosity will increase in each population as a result of migration.Explanation / Answer
Genetic diversity within each population will remain lower than a situation without migration.
Allele frequencies will diverge between these populations.
Homozygosity will increase in each population as a result of migration.
Explanation:
Migration is nothing but movement of alleles between population and as per the Hardy-Weinberg Equilibrium, mutation, chance effects from a mating population; migration and selection will bring a change in the allele frequencies.
We can say that there is a positive correlation between population size and genetic diversity and genetic variation is caused by either random mating or mutation.
Migration may increase the genetic variability, but will not allow the species to diverge and there will be a increase in the homozygosity in the population.
