Fig. 7 in Hybridization Between the Endangered Unisexual Gray-Checkered Whiptail Lizard (Aspidoscelis dixoni) and the Bisexual Western Whiptail Lizard (Aspidoscelis tigris) in Southwestern New Mexico

Fig. 7. Pattern of morphological variation expressed by the distribution of scores on the first two principal components extracted from a correlation matrix of seven meristic characters of 30 specimens of Aspidoscelis from Antelope Pass, Hidalgo County, New Mexico. The specimens include representatives of two species (A. dixoni C and A. t. punctilinealis) and hybrids between them. Note that the three hybrids cluster most closely to their maternal parent.
