The relationship between temperature and the proportion of male hatchlings for the Cape Domett population. (A) TSD model fitted using all available data (Hill equation; red line) and the consensus model fitted using a subset of the field data (black line). (B) Shows the consensus model and only those data used for model fitting (laboratory data = open circles; field data = closed circles), with the pivotal temperature of 29.4°C indicated by the dotted line and the boundaries of the TRT by dashed lines.
