For instance, the key genetic elements that mediate the effect of environmental temperature in TSD systems remain elusive. The evolution of sex determination remains an evolutionary enigma, yet this developmental process is critical for the production of sex ratios and consequently for the dynamics and evolutionary potential of populations [ 92 ].

In contrast, Dax1 expression is female-biased in birds and monomorphic in several TSD taxa including the green sea turtle Lepidochelys olivaceaChelydra and Trachemys reviewed in [ 42 ]. In particular, DAX1 is a known regulator of gonadal development in mice and other mammals, considered to be an "anti-testis" gene, although this may approach may prove to be too simplified.
