ALL BUT ONE of the statements below helps to describe gene flow. That is
A)
B)
Without genetic variation, some of the basic mechanisms of evolutionary change cannot operate.
There are three primary sources of genetic variation:
1. Mutations
II. Gene flow
III. Sexual reproduction
D)
It depends on a chance event that changes the gene pool.
It can reduce the genetic differentiation between the two groups.
It involves the movement of alleles from one population to another.
It includes migration or the movement of individuals between populations.
Some mutations always occur from generation to generation. But most mutations do not persist over time in the gene
pool. Which mutation is MOST likely to become established and persist in a species?
