Changes in allele frequencies in a population or species that occur over a relatively short time rather than millions of years is an example ofMultiple choice question.macroevolution.adaptation.microevolution.coevolution.

The small, genetic changes that occur from generation to generation within a population or species are calledMultiple choice question.dimorphism.microevolution.equilibrium.macroevolution.

Microevolution can be described as ____.Group of answer choicesThe successful interaction between an organism and the environmentThe blending of acquired characteristics from one generation to the nextA change in allele frequencies from one generation to the nextThe differences that exist between individuals or populations of the same speciesNone of the above

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.

An example of macroevolution would be the appearance of a newMultiple choice question.phenotype in finches.species of finch.allele in a finch species.genotype in a finch population.
