FIGURE 6 in Laboratory Hybridization among North American Whiptail Lizards, Including Aspidoscelis inornata arizonae × A. tigris marmorata (Squamata: Teiidae), Ancestors of Unisexual Clones in Nature

FIGURE 6. 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 three hybrids, 18 specimens of A. i. arizonae (including the maternal parent of the hybrids), 18 specimens of A. t. marmorata (including the paternal parent of the hybrids), and 11 specimens of the unisexual A. neomexicana. All samples represent populations in the vicinities of those from which the parents of the hybrids were collected. Note that the three hybrids are intermediate to their individual parents and that A. neomexicana most closely resembles its maternal progenitor species, A. t. marmorata on PC1.
