The term gene pool refers to all the
A. alleles, genes, chromosomes, and genotypes within a breeding population.
B. mutations in a breeding population.
C. alleles, genes, chromosomes, and genotypes of the animal kingdom.
D. processes of achieving a perfect fit to the environment.
E. mechanisms of competition over strategic resources.
Question 2
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.
