A type of genetic drift in which a population's size drops rapidly over a short period of time, causing the loss of many alleles, is called aMultiple choice question.bottleneck effect.polygenic effect.founder effect.migration effect.

A change in allele frequency following a dramatic reduction in the size of a population is calledA.disruptive selection.B. bottleneck effect.C.stabilizing selectionD.genetic drift.

A change in allele frequencies that occurs by chance and that tends to eliminate alleles in a population rather than increase diversity is calledMultiple choice question.genetic drift.selection.migration.nonrandom mating.

Which type of genetic drift occurs when many members of a population die, resulting in a great loss of genetic diversity?Multiple Choicethe founder effectthe bottleneck effectthe directional effectthe selective effectNone of the answer choices are correct.

The loss of genetic variation that occurs when a new population is established by a very small number of individuals from a larger population is ------------------ Group of answer choicesNonepopulation bottleneckPolyploidyFounder's effect

When a population size drops rapidly over a short period, causing a loss of many alleles that were present in the larger ancestral population, this is referred to as the effect.
