Meiosis II involves the separation of sister chromatids in both sexual and parthenogenetic species. Farmers rely on both traits: sexual reproduction produces fruit, whereas asexual reproduction provides breeders with clones of useful strawberry varieties. All chameleons lay eggs after a 3-6 week gestation period. The eggs contain no male DNA, so the process is called asexual reproduction.

In some circumstances, there may be additional benefits to . In 2011, researchers from the Stowers Institute for Medical Research in Kansas City found that, while it is not uncommon for asexual reptiles to develop eggs into embryos without fertilization, the female whiptails cells gained twice the usual number of chromosomes during the process. That means that whiptail eggs get the same number of chromosomes and resulting genetic variety as those of lizards that reproduce sexually. chameleon, still in a protective membrane, because there is no true "Sex steroid hormones during the ovarian cycle of an all-female, parthenogenetic lizard and their correlation with pseudosexual behavior."
