Cnemidophorus is a genus of lizards which belong to the family of Teiidae, which are commonly referred to as Whiptail Lizards or Racerunners.
In some of the Cnemidophorus species, there are no males, and they reproduce through parthenogenesis. This has been observed in bees and aphids, but very rare in vertebrates. Those species without males are now known to originate through interspecific breeding. When a female from one species mates with a male from another, instead of producing sterile offspring (the normal result of inter-species mating), an all-female litter is produced that has double the chromosomes, and thus are born fertile. Sometimes, these females mate with other males, producing offspring with triple the chromosome count. Over 30% of the Cnemidophorus genus are parthenogenic.
