The influence of varying egg geographic origin on resulting offspring sex ratios was also analyzed. Both field and laboratory-incubated eggs required approximately 150 degree-hours to produce at least 50% female offspring. Those eggs originating from more southern locations required fewer degree hours to produce a given percentage of female turtles. In other words, more female offspring from lower latitudes were produced within a particular temperature treatment than resulted from more northern latitudes.
