  • Title: Absence of temperature-dependent sex determination in congeneric sexual and parthenogenetic Cnemidophorus lizards.
    Author: Crews D.
    Journal: J Exp Zool; 1989 Dec; 252(3):318-20. PubMed ID: 2607330.
    Abstract:
    Eggs from congeneric gonochoristic and parthenogenetic whiptail lizards were incubated at various temperatures. There was no significant deviation from a sex ratio of one-half in the sexual species at any temperature, whereas no males were produced in the parthenogenetic species. Temperature-dependent sex determination appears to be completely absent in these lizards.
