Which process causes traits that enhance survival or reproduction to increase in frequency over time?

Adaptive evolution

The founder effect

Genetic drift

Natural selection (correct)

What is genetic drift?

The process where genetic variation is reduced through loss of alleles

The process where traits that enhance survival or reproduction increase in frequency over time

The process where allele frequencies fluctuate unpredictably from one generation to the next (correct)

The process where a few individuals become isolated from a larger population

How does genetic drift affect genetic variation?

It has no effect on genetic variation

It stabilizes genetic variation

It reduces genetic variation through loss of alleles (correct)

It increases genetic variation through the introduction of new alleles
