Indicate which organisms in the following examples would be considered separate species according to the biological species concept.

- Lions and tigers have been successfully interbred in captivity to produce viable offspring; hybrid males are infertile while females can be fertile. In the wild, lions live in Africa, tigers live in Asia, and the two species do not interbreed.

- Black bears in the United States can have coat colors ranging from blonde to jet black. Blonde colored bears and black colored bears occupy the same habitat and interbreed successfully.

- Different species of leopard frogs in the eastern United States look the same and can mate to produce a fertilized egg, but the embryo does not develop past the early stages.

- Different species of Darwin's finches can interbreed in captivity to produce viable, fertile offspring, but they differ in their mating song patterns, so they are not attractive mates in the wild.

Which of the following would be an example of a postzygotic isolating mechanism?

Which of the following would be considered an example of a postzygotic isolating mechanism? Answer: e. The failure of a fertilized egg to develop normally is an example of a postzygotic isolating mechanism.

Which is an example of a postzygotic isolating barrier?

Postzygotic barriers include the creation of hybrid individuals that do not survive past the embryonic stages ( hybrid inviability ) or the creation of a hybrid that is sterile and unable to produce offspring ( hybrid sterility ).

What are post

Any factor that tends to reduce or prevent interbreeding between genetically divergent populations or species, but functioning after fertilization has occurred; includes hybrid inviability, hybrid sterility, and hybrid breakdown.

Which of the following is an example of a pre zygotic isolating mechanism?

A mating between two species in which the zygote dies early in its development (i.e. dies during embryogenesis) is a form of pre-zygotic isolating mechanisms.
