Fig 1. Sex-specific effects of yolk androgens in great tits.

Fig 1

Difference in A) fledging size and B) fledging mass of male and female great tit nestlings originating from an egg with experimentally increased yolk testosterone content (T) or a control egg (C). Means ± 1 SE of the residuals (+1) of an analysis that included nest ID, brood size and hatching date are shown. Size difference between C and T males: P = 0.021, size difference between C and T females: P = 0.477; mass difference between C and T males: P = 0.026, mass difference between C and T females: P = 0.136.
