Which of the following is an example of postzygotic isolation?Multiple choice question.Mating between a sheep and a goat produces an embryo that fails to develop.Several frog species that occupy the same habitat remain separate species because they breed at different times of year.Lions and tigers do not hybridize in the wild because they are ecologically isolated.A male moth cannot detect pheromones produced by females of different moth species.

When populations are only partially reproductively isolated, which of the following may occur?Multiple choice question.Postzygotic isolating mechanisms will act to prevent the survival and reproduction of hybrid offspring if a zygote is formed.Even though individuals are interbreeding, prezygotic and postzygotic isolating mechanisms ensure that hybrids do not survive and reproduce.Prezygotic isolating mechanisms will act to prevent the formation of a zygote if postzygotic isolating mechanisms fail.Despite prezygotic and postzygotic isolating mechanisms, some individuals may survive and reproduce.Need help?

The inability of fertilized eggs to develop following matings between different species of leopard frogs is an example of which of the following?Multiple choice question.Mechanical isolation.Postzygotic isolation.Prevention of gamete fusion.Behavioral isolation.

Which type of prezygotic isolating mechanisms occurs when reproduction is prevented because species mate at different times of the day, seasons, or year?Multiple choice question.Temporal isolationMechanical isolationBehavorial isolationEcological isolation

What type of isolation occurs when members of one species are unable to successfully interbreed with members of another species?Multiple choice question.BiologicalReproductivePhysiologicalEvolutionary

How do postzygotic isolating mechanisms prevent successful interspecies hybridization?Multiple choice question.The egg cannot be fertilized by sperm of another species following a successful mating attempt.Members of different species attempt to mate but are unsuccessful due to anatomical differences.Although fertilization is successful, the resulting hybrid is unable to develop or reproduce.Members of different species come into contact, but do not recognize one another as potential mates.
