Parthenogenesis occurs in several (~30) squamate groups.
Most studied _ teiid genus Cnemidophorus.
- ~45 Cnemidophorus species _ ~ 15 are parthenogenetic
- Unisexual species may be diploid or triploid
- Pseudocopulation: one individual plays the role of male.
- Females involved in pseudocopulation produce more eggs _ behavior enhances gonadal activity
Other squamates:
- some lacertids, some geckos, and the snake Rhamphotyphlops braminus.
