FIGURE 7 in Laboratory Hybridization among North American Whiptail Lizards, Including Aspidoscelis inornata arizonae × A. tigris marmorata (Squamata: Teiidae), Ancestors of Unisexual Clones in Nature

FIGURE 7. Pattern of morphological distinctiveness expressed by the distribution of canonical variate scores derived from a canonical variate analysis of seven meristic characters of three a priori groups: 18 specimens of A. i. arizonae (including the maternal parent of the laboratory hybrids), 18 specimens of A. t. marmorata (including the paternal parent of the hybrids), and 11 specimens of A. neomexicana. All samples represent populations in the vicinities of those from which the parents of the hybrids were collected. The three laboratory hybrids were included in the CVA as unassigned, for classification to the a priori group that each most closely resembled. Note the position of the hybrid group intermediate to A. i. arizonae, A. t. marmorata, and A. neomexicana clusters. This suggested that the hybrid group itself is distinctive, which was verified by a followup CVA (not illustrated, but see text).
