Posted by: Sunherp at Tue May 6 14:00:13 2014 [ Report Abuse ] [ Email Message ] [ Show All Posts by Sunherp ] Lampropeltine Colubrids have defined and identifiable sex chromosomes. They use the ZW system like birds, rather than the XY system we mammals use. As such, their sex determination is genetic (frequently called GSD) rather than temperature-dependant like that seen is some geckos and some Chelonians. Hope that helps.
