The concept of gene flow is demonstrated when a cow is driven off from its herd, joins another herd, and reproduces. when the cow contributes to the gene pool of the new herd, which of these most likely increases?

natural selection

reproductive mutations

environmental variation

genetic variation

The concept of gene flow is demonstrated when a cow is driven off from its herd, joins another herd, and reproduces. When it contributes Sachem pollution of new herd, the genetic variation is very likely to increase.

Hence the correct answer to the question is option D.
