In many reptiles, sex determination is dependent not on sex chromosomes but rather environmental conditions such as temperature. Species that use temperature are said to have temperature-dependent sex determination (TSD). One known mechanism for TSD in some species is the temperature-dependent activity of an enzyme, aromatase, that acts to convert androgens (hormones that promote male development) to estrogens (hormones that promote female development). You have begun to study two species of lizards that seem to use TSD. You collect eggs from both species and rear them at various temperatures with and without applied fadrozole, a chemical that specifically inhibits the activity of aromatase. Your results are as follows. Based on these results, what can you conclude about sex determination in species A and species B?
