Figure 1.

Morphological differences among sexes of Central Bearded Dragons (Pogona vitticeps). Data are shown for three sexes: males in which genetic and phenotypic sex are concordant (ZZm), females in which genetic and phenotypic sex are concordant (ZWf), and sex-reversed females which are genetically male, but with functional female gonads (ZZf). Data for morphological traits are shown by residual values from the linear regression of ln trait (tail length or body mass) against ln snout-vent length (SVL), for ease of interpretation, but statistical tests in the text are based on ANCOVA. (a) Relative tail length and (b) relative body mass.
