Gene flow:Question 1Select one:a.occurs when individuals move into or out of a population.b.must not occur for a population to be at Hardy-Weinberg equilibrium.c.is a force of evolution.d.all of the above
Solution
d. all of the above
Explanation:
a. Gene flow occurs when individuals move into or out of a population. This is because these individuals can carry genes that are not present in the population they are moving into, or they can remove genes from the population they are leaving.
b. For a population to be at Hardy-Weinberg equilibrium, gene flow must not occur. The Hardy-Weinberg equilibrium is a state where allele frequencies in a population remain constant from generation to generation. This can only happen if there are no forces of evolution at work, which includes gene flow.
c. Gene flow is indeed a force of evolution. By introducing new genes into a population or removing genes from it, gene flow can change the genetic makeup of that population. Over time, these changes can lead to evolution.
