A Species of Lizard Is Found on the Eastern and Western

Multiple Choice

A species of lizard is found on the eastern and western sides of part of a mountain range.On both sides,individual populations are small.On the western side,individual populations are relatively close together and males move extensively among populations to breed.On the eastern side,however,populations are farther apart and males seldom move among more than one or two adjacent populations to breed.If you were to study the genetic diversity of western and eastern populations,which pattern would you expect to find?

A) Each of the western and eastern populations would have a limited number of the total alleles available in the species.Combined,however,the western populations will have more different alleles than will the combined eastern populations.
B) Each of the western and eastern populations will have all of the available alleles.In each western population,the alleles will be equally frequent.In each eastern population,one allele will be far more frequent than the others.
C) The eastern populations will be,on average,more genetically diverse than the western populations.Each western population will have only a limited number of alleles,and one will be far more frequent than the others.
D) Each western population would be genetically diverse,although the allele frequencies might differ from one population to the next.Eastern populations would be less diverse,and some populations will have only a limited number of the total alleles available in the species.
E) All of the above are equally reasonable patterns to expect given the information provided.
