Question

What is internal fertilisation explain with example

Answer 1

Internal fertilization is the union of an egg cell with a sperm during sexual reproduction inside the body of a parent. For this to happen there needs to be a method for the male to introduce the sperm into the female's reproductive tract. In mammals, reptiles, some birds, some fish and certain other groups of animals, this is done by copulation, the penis or other intromittent organ being introduced into the vagina or cloaca.[1] In most birds, the cloacal kiss is used, the two animals pressing their cloacas together while transferring sperm.
