A review of sex determining mechanisms in geckos in Aurora

Note that only some Gehyra australis populations possess heteromorphic sex chromosomes [ King, ]. Kluge AG. Heteronotia binoei [ Moritz, b ] and Lepidodactylus lugubris [ Volobouev and Pasteur, ]. It is possible that the 6 cells with 2n less than 41 were the result of some technical inaccuracy.

These taxa can be coded as having either one of these states using the parsimony criterion. Sex determining mechanisms are labeled as either TSD, temperature dependent sex determination, or GSD, genetic sex determination.

Some taxa have master-switch sex-determining genes that are highly conserved, such as the Sry gene in nearly all mammals [77]. Additional L. It is also possible that the additional chromosomes may be supernumerary or B chromosomes.

The pathways that control sexual development have been well characterized at the molecular level in D. Gamble T. Sex determining mechanisms are well characterized for several a review of sex determining mechanisms in geckos in Aurora of Eublepharidae, most notably TSD in the leopard gecko, Eublepharis macularius.
