TRIPLOID IN PARTHENOGENETIC SPECIES OF THE TEIID LIZARD, GENUS CNEMIDOPHORUS.

L A PENNOCK.   

Abstract

Mitotic figures from the bone marrow of three parthenogenetic species of Cnemidophorus (whiptail lizards) exhibit chromosome numbers in the triploid range. The species are C. velox with 68 chromosomes, C. tesselatus with 69, and C. exsanguis with 70. A fourth parthenogenetic species, C. perplexus, has 46 chromosomes, the same number as the bisexual subspecies C. tigris septentrionalis.
