Exam 17: Processes of Evolution

__________ is rapid diversification into new species that occupy novel niches.

Classification.For the following statements select the best choice of the four evolutionary processes listed below. a.mutation b.gene flow c.genetic drift d.natural selection -This process produces new genetic variation within a species.

__________ occurs in different patterns depending on the species and selection pressures.

MATCHING Matching.Choose the most appropriate letter for each. a.a reference point that implies stability of gene frequencies through generations b.encompasses all of those actually or potentially interbreeding populations that are reproductively isolated from other such groups c.the genes of an entire population d.the frequency of homozygous dominants in a population e.the frequencies of dominant and recessive alleles in a population f.the frequency of heterozygotes in a population g.the frequency of homozygous recessives in a population h.heterozygote advantage in regions where malaria is found i.pesticide-resistant pests -p + q
