Subjects Evolutionary genetics Experimental evolution Genome evolution. For example, sex in the fruit fly, Drosophila melanogaster , is determined by the ratio of numerator and denominator genes found on the X chromosomes and autosomes, respectively [ Cline, ].

  • Sex Determination. Although the specific molecular mechanism that determines sex has not been revealed in any reptilian species, general modes of sex determination can be described [Bull, ; Janzen and Paukstis, ].An individual's genotype at one or more loci can control whether it develops testes or ovaries. 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:
