Six species of lizards in the genus Cnemidophorus, Teiidae, have been found to be all-female or virtually all-female. The species are C. costatus exsanguis Lowe, C. deppei cozumelus Gadow, C. inornatus Baird (western population), C. perplexus Baird and Girard, C. tessellatus (Say), and C. velox Springer. It is hypothesized that the explanation of these virtually all-female populations is genetic.
