Assignment as GSD to species exhibiting equal sex ratios at several constant incubation temperatures but no sex chromosomes should be treated with more caution. Some features of the site may not work correctly. Adriosaurus and the affinities of mosasaurs, dolichosaurs, and snakes.

Transitions between male and female heterogamety are apparent and even more numerous under the molecular trees as well, but the direction in some of them depends on the resolution of polytomies Figs 23. Receive exclusive offers and updates from Oxford Academic.

  • Sex Determination in Reptiles Daniel A. Warner Iowa State University, Ames, IA, USA SUMMARY The sex-determining mechanisms (SDMs) of reptiles are remarkably diverse, ranging from systems that are under complete genetic control to those that are highly dependent upon temper-atures that embryos experience during development. Because. Most research on the molecular biology of sex determination in reptiles describes expression patterns for orthologs of mammalian sex-determining genes. Many of these genes have evolutionarily conserved expression profiles (i.e., DMRT1 and SOX9 are expressed at a higher level in developing testes vs. developing ovaries in all species), which Cited by:
