Evidence from the flour beetle experiments discussed in the text provides support for genetic drift resulting in
A)random change in allele frequencies.
B)fixation of one or more alleles.
C)loss of genetic diversity.
D)greater change in allele frequencies in smaller populations.
E)all of these.

Question

Quizplus · Accepted Answer

The flour beetle experiments provide evidence for all of the options listed. The experimenters observed random changes in allele frequencies over time (A), fixation of certain alleles in some populations (B), loss of genetic diversity in some populations (C), and greater fluctuations in allele frequencies in smaller populations (D). Therefore, the best choice is E, which includes all of these options.
