Lactate dehydrogenase isozymes in parthenogenetic teiid lizards (Cnemidophorus)

Science. 1968 May 31;160(3831):1004-5. doi: 10.1126/science.160.3831.1004.


Heterozygosity occurs at the lactate dehydrogenase b-locus in two diploid parthenogenetic species of Cnemidophorus. Each such species produces two different B subunits, one of which is also found in two sexual species and in two triploid parthenogenetic species; the other occurs also in a third sexual species. Interspecific hybridization between sexual species carrying different b-alleles and producing different B subunits may be responsible for the heterozygosity at the lactate dehydrogenase b-locus in diploid parthenogenetic Cnemidophours.
