Any factor that contributes to the change in allele frequency in a breeding population from generation to generation is considered a mechanism of genetic evolution. Those mechanisms are
A. sexual selection, mutation, and human biological plasticity.
B. independent assortment, recombination, and mutation.
C. random genetic drift and random gene flow.
D. phenotypic straining through the organism's development and mutations across the generations.
E. natural selection, mutation, random genetic drift, and gene flow.
Question 2
Human biology
A. is no longer affected by evolutionary processes.
B. remains the best explanation for genetic evolution.
C. is all in the genes.
D. is 75 percent genotype and 25 percent phenotype.
E. is not set at birth but has considerable plasticity.
