Early on in this chapter,we learned that evolution refers to descent with modification over generations.Geneticists,however,have an even more specific definition of evolution:
A) directional selection of the fittest alleles in a breeding population.
B) a change in gene frequency; that is, in the frequency of alleles in a breeding population from generation to generation.
C) a change in the gene frequency within the DNA of a single individual organism.
D) the survival of the chemically fittest allele in the gene pool.
E) a change in gene frequency caused by either chromosomal rearrangement or recombination.

Question

Quizplus · Accepted Answer

Geneticists define evolution as a change in gene frequency, or the frequency of alleles in a breeding population from generation to generation. This definition encompasses the overall process of descent with modification, as genetic changes that occur over time can result in the development of new species.
