I'm just trying to find out whether the male side-blotched lizard is the hetero- or homogametic sex in side-blotched lizards (Uta stansburiana) - some reptiles are ZW system (female heterogamete) and some are XY (male heterogamete).

Lizards of the genus Uta are apparently male heterogametic (XY) ( Pennock et al. 1969) [1]. The XY system seems to be the most common mode of sex determination in iguanid lizards ( Kasahara et al. 1983 [2]).
