Question

Your friend is telling you that evolution and natural selection are the same thing. Compare how genetic drift and gene flow are different from natural selection.

a) Genetic drift and gene flow involve random processes, while natural selection is based on adaptation.
b) Genetic drift and gene flow are terms used in mathematics, while natural selection is a biological concept.
c) Genetic drift and gene flow are synonyms for natural selection.
d) Genetic drift and gene flow occur over short periods, while natural selection operates over long periods.

Answer 1

Genetic drift and gene flow involve random processes, while natural selection is based on adaptation.

Step-by-step explanation:

Genetic drift and gene flow involve random processes, while natural selection is based on adaptation. Genetic drift refers to the change in allele frequencies within a population due to random events, such as the death of individuals who carry a particular allele. Gene flow, on the other hand, is the movement of alleles between populations through the migration of individuals or transfer of gametes. Both genetic drift and gene flow can bring about changes in the genetic makeup of a population, but they do so through random processes, whereas natural selection is a non-random process that acts based on the adaptation of individuals to their environment.
