 While sex hormones have been observed to be influenced by temperature, thus potentially altering sexual phenotypes, specific genes in the gonadal differentiation pathway display temperature influenced expression.In some species, such important sex-determining genes as "DMRT1" and those involved in the Wnt signalling pathway could potentially be implicated as genes which provide a mechanism (opening the door for selective forces) for the evolutionary development of TSD.While aromatase is involved in more processes than only TSD, it has also been shown to play a role in certain tumor development.
