Study Guide: Answer KeyChapter 14: Nonadaptive Evolution and SpeciationUrban Evolution: How cities are altering the fate of speciesDriving Question 1:What is a gene pool?Why should you care?Test Your Vocabulary:
Match the following definitions to the terms they describe:[POPULATION GENETICS] The study of the genetic makeup of populations and how the genetic composition of a population changes[GENE POOL] The total collection of alleles in a population[ALLELE FREQUENCY] The relative proportion of an allele in a population[NONADAPTIVE EVOLUTION] Any change in allele frequency that does not by itself lead a population to become more adapted to its environment; the mechanisms of nonadaptive evolution are mutation, genetic drift, and gene flow1.Define “gene pool.”a.What is a gene pool? b.Can different populations of the same organism have different gene pools? Why or why not? c.
Can you swim in a gene pool?
2.Relate gene pool and allele frequencies to evolution.a.For evolution to occur, what must happen to a population’s gene pool? b.Will a change in allele frequencies always result in a beneficial evolutionary change for the population? Review Questions
