Question

Distinguish zygotic from gametic gene flow and offer an example of a taxon in which each is likely to be the dominant form of gene flow.

Answer 1

Zygotic gene flow is the movement of alleles through individuals, while gametic gene flow is the movement of alleles through gametes. In bird species that migrate, zygotic gene flow is likely to be dominant. In marine species that release gametes into the water, gametic gene flow is likely to be dominant.

Step-by-step explanation:

Zygotic gene flow refers to the flow of alleles in and out of a population through the movement of individuals, while gametic gene flow refers to the flow of alleles through the movement of gametes. An example of a taxon where zygotic gene flow is likely to be dominant is a species of bird that migrates across different geographic locations. The movement of individual birds between populations can result in the flow of alleles. An example of a taxon where gametic gene flow is likely to be dominant is a marine species that releases gametes into the water. The currents can carry the gametes to other populations, facilitating the flow of alleles.
