A Proof of Female Heterogamety in a Lacertid Lizard, Ophisops elegans

Abstract
The diploid number of chromosomes in Ophisops elegans in 38-36 macro- and 2 micro-chromosomes in the males and 35 macro and 3 micro-chromosomes in the females. The sex determining mechanism is of the ZZ:ZW type. The Z-chromosomes are represented by the smallest pair of macro-chromosomes and the W-chromosome consists of the micro-chromosome which is even smaller than the pair of micro-chromosomes (pair 19).
