Question

Quizplus · Accepted Answer

Terrestrial vertebrates and some fish have evolved internal fertilization, where male gametes are introduced into the female reproductive tract, as opposed to external fertilization where the fusion of gametes occurs outside the body. Asexual reproduction involves the creation of offspring without the involvement of gametes, so it is not relevant in this context. Synchronous fertilization is not a type of fertilization, but describes when the eggs of females and the sperm of males are released and meet simultaneously in the environment, as is the case in most external fertilization.
