Summary Introduction
Introduction: The species in reproductive isolation impedes the members of both the species from interbreeding to the species that produce fertile offspring. These barriers stop the gene flow between the species, and thus limit the formation of hybrids.

A. Reproductive isolation doesn't take outgroups into account. B. This definition overlooks artificial reproduction, such as in zoos. C. This definition excludes organisms that reproduce asexually. D. Reproductive isolation can be accomplished in a variety of ways.arrow_forwardWhich of the following would be a good example of premating reproductive isolation? A. Cross-fertilizations between the gray treefrogs, Hyla versicolor and H. chrysoscelis result in a high degree of mortality prior to hatching of hybrid eggs. B. The mule, a hybrid between horses and donkeys is viable, but sterile. C. Males of H. versicolor produce an advertisement call with a much slower pulse rate than males of H. chrysoscelis and females use pulse rate differences to avoid mating with the wrong species. D. Hybrid offspring are produced from matings between leopard frogs and green frogs, but usually die before the tadpoles metamorphose into froglets.arrow_forward
