The process of oogenesis is often described as theproduction of a haploid egg by meiosis, but in someanimals, including humans, this description is notentirely accurate. Explain.

meiosis is the process where organisms producé 81isping called9ametes Cells are a combination of reproductive cells, ova and spermatozoa that are produced by a unique process of cell division called. Except for it is virtually impossible for two animals to or have exactly the same genetic makeup. The genetic material in the body's cells is contained in the in the form of coiled masses of DNA called are the male reproductive cells are formed. The These are the organs where the male Testes are generally in shape and their varies among species. The testes develop near the in the portion of the abdomen. The testes are attached to their permanent home in the scrotum, by a band of connective tissue called the is the process by which the seminiferous tubules of the testes produce sperm. The inability of the penis to retract into the prepuce Is called The structure that protects the penis in animals is the link the testes with the rest of the body. They are tube-like, that contain blood…
