"In 15 of the Cnemidophorus species there are no males. They reproduce without fertilization, a process known as parthenogenesis of "virgin birth"."

"where AP has been described, females have dissimilar sex chromosomes (ZW), while males have two copies of the same chromosome (ZZ). In AP, if the egg and the second polar body each contain a Z chromosome, when they are combined, a male offspring will be produced. If they both contain a W chromosome (a 50% chance), the egg will be non-viable (WW). This is what causes the high proportion of infertile eggs in AP parthenogenesis."

"An interesting aspect to reproduction in these asexual lizards is that mating behaviors are still seen even though the populations are entirely female. One female plays the role formerly played by the male and mounts the female that is about to produce eggs."
