B)mating with dominant phenotypes.
C)hybridization between individuals of adjacent populations.
D)removing the barriers between the populations.
E)physical movement of genes within an individual by transposons.

Question

Quizplus · Accepted Answer

Hybridization between individuals of adjacent populations can result in gene flow. This occurs when individuals from two different populations breed and produce hybrids that have a mixture of genes from both populations. Over time, if these hybrids continue to breed with individuals from both populations, the genes from the two populations will become more mixed, leading to gene flow. Migration (A) can also lead to gene flow, but it specifically refers to the physical movement of individuals from one population to another, rather than the mixing of genes through hybridization. Mating with certain trait-containing individuals (B) may increase the frequency of certain genes in a population, but it does not necessarily lead to gene flow between two populations. Removing barriers between populations (D) could potentially lead to an increase in gene flow, but this would depend on whether individuals from the two populations are able to breed and produce viable offspring. The physical movement of genes within an individual by transposons (E) does not result in gene flow between populations.
