Which mechanism(s) are responsible for introducing new alleles into a population's gene pool? A) gene flow B) emigration C) niche shift D) natural selection

Respuesta :

A) gene flow because blank blank blank

Answer:

A) gene flow

Explanation:

Through gene flow, populations exchange alleles, and can therefore acquire new alleles that they did not have before. To ensure gene flow (of alleles) between two different populations, there must be reproduction among their individuals. That is, individuals from population 1 must reproduce with individuals from Population 2.
