Animal Reproduction Quiz

In sexual reproduction, the fusion of haploid gametes forms a diploid cell, while in asexual reproduction, new individuals are generated without the fusion of egg and sperm.

Some examples of asexual reproduction in animals include binary and multiple fission, budding of hydra, asexual reproduction by fragmentation, and parthenogenesis.

Parthenogenesis is extremely rare in vertebrates, but has been confirmed in a handful of sharks, snakes, lizards, and birds.

<p>Parthenogenesis is a form of reproduction in which offspring develop from unfertilized eggs. It can be induced by environmental conditions or through artificial means by researchers.</p> Signup and view all the answers

<p>Hormones regulate reproductive cycles in animals by responding to environmental cues and controlling the secretion of other hormones. They ensure that animals reproduce only when sufficient energy sources are available and when environmental conditions favor the survival of offspring.</p> Signup and view all the answers

<p>External fertilization occurs when the female releases eggs into the environment, where they are fertilized by the male. Internal fertilization occurs when sperm is deposited in or near the female reproductive tract and fertilizes eggs within the tract.</p> Signup and view all the answers
