Gene flow:

Question

Gene flow:

Quizplus · Accepted Answer

Gene flow refers to the movement of genes from one population to another, which can spread certain alleles throughout a species. This can increase genetic diversity and therefore evolutionary fitness, rather than limiting it as option E suggests. Gene flow can also potentially prevent isolation of populations, making option C incorrect. Option A is also incorrect, as gene flow involves migration rather than preventing it. Option D is incorrect, as gene flow is one of the mechanisms driving evolution rather than negating it.
