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.

Homozygosity will increase in each population as a result of migration. Allele frequencies will diverge between these populations. Genetic variation between the populations will be very high. Genetic diversity within each population will remain relatively high compared to a situation without migration. Allele frequencies will remain similar between these populations. Genetic diversity within each population will remain lower than a situation without migration.

Explanation / Answer

a). Homozygosity will increase in each population as a result of migration. ----> FALSE (Bidirectional migration increases the genetic diversity)

b). Allele frequencies will diverge between these populations. -----> FALSE (Bidirectional migration reduce the differences in allele frequencies)

C). Genetic variation between the populations will be very high. ---> FALSE (Bidirectional migration increases the genetic diversity within the population but reduces between the population)

D). Genetic diversity within each population will remain relatively high compared to a situation without migration. ---> TRUE

E). Allele frequencies will remain similar between these populations. -----> TRUE

F). Genetic diversity within each population will remain lower than a situation without migration. ----> FALSE
