The genetic diversity of sexually produced offspring is thought to give species a better chance of surviving in an unpredictable or changing environment. Species that reproduce sexually must maintain two different types of individuals, males and females, which can limit the ability to colonize new habitats as both sexes must be present.

One of the most prominent features of the body plan of true animals is that they are morphologically symmetrical. This means that their distribution of body parts is balanced along an axis. Additional characteristics include the number of tissue layers formed during development, the presence or absence of an internal body cavity, and other features of embryological development, suc

Other unusual systems include those of the green swordtail (a polyfactorial system with the sex-determining genes on several chromosomes) [13] ; the juvenile hermaphroditism of zebrafish, with an unknown trigger; [13] and the platyfish, which has W, X, and Y chromosomes.
