Document Summary

Which of the following describes the most likely order of events in speciation: divergence, genetic isolation, genetic drift, genetic isolation, divergence, genetic drift, genetic isolation, genetic drift, divergence, genetic drift, genetic isolation, divergence. The correct answer is: genetic isolation, genetic drift, divergence. Dog breeders maintain the purity of breeds by keeping dogs of different breeds apart when they are fertile. This kind of isolation is most similar to which of the following reproductive isolating mechanisms: reduced hybrid fertility, gamete isolation, mechanical isolation, habitat isolation. If speciation occurs with the production of two or more species in a small area, ____ is (are) probably responsible: either sympatric or allopatric speciation, both sympatric and allopatric speciation, only sympatric speciation, only allopatric speciation. The correct answer is: an increase in chromosome number due to hybridization of different species. The correct answer is: it causes allele frequencies to drift up or down randomly.
