Read the Chapter Concepts list on page 647. All these pertain to the principles of population genetics and the evolution of species. Write a short essay describing the roles of mutation, migration, and selection in bringing about speciation.
▪Most populations and species harbor considerable genetic variation.
▪Th is variation is reflected in the alleles distributed among populations of a species.
▪The relationship between allele frequencies and genotype frequencies in an ideal population is described by the Hardy-Weinberg law.
▪Selection, migration, and genetic drift can cause changes in allele frequency.
▪Mutation creates new alleles and changes allele frequencies only in very small populations.
▪Nonrandom mating changes population genotype frequency but does not change allele frequency.
▪A reduction in gene flow between populations, accompanied by selection or genetic drift, can lead to reproductive isolation and speciation.
▪Genetic differences between populations or species are used to reconstruct evolutionary history.
