The Giant Red Sea Urchin and the Purple Sea Urchin cohabit the rocky intertidal zones along the western United States and cannot interbred because their gametes are genetically/chemically incompatible. This is an example of which of the following?Multiple choice question.Behavorial isolationPostzygotic isolationPrevention of gamete fusionEcological 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

If you separate the blastomeres of a sea urchin, since their developmental path is not predetermined, each blastomere can become a complete sea urchin. What sort of development is this?Multiple choice question.MosaicRegulativeIntermediateDeterminate

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.

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

Which of the following occurs when different species are isolated by their mechanics, i.e., the genitalia of the males and females may have different shapes, sizes of locations?Multiple choice question.Behavorial isolationTemporal isolationEcological isolationMechanical isolation
