The process of genetic drift describes

Compared with the original population, an isolated “founder” population of a species will usually

The close resemblance between the viceroy butterfly, an inoffensive edible species, and the monarch butterfly, a poisonous inedible species, is a good example of

Hummingbirds use their long beaks to drink nectar from flowers. In turn, they carry the pollen from flower to flower, assisting with the reproduction of the flowers. What relationship does this describe?

Differences of bird songs between two closely related species of meadowlarks represent a mechanism for

The process by which a portion of a population moves into a new environment and diverges from the parent population, resulting in the formation of two separate species occurs. When gene flow is re-established, the reproductive barriers between the two species are weak. This results in

The assumptions of the Hardy-Weinberg equilibrium include all of the following EXCEPT
