Increased egg estradiol concentration feminizes digit ratios of male pheasants (Phasianus colchicus).

Die Naturwissenschaften - 1 Mar 2007

Saino N, Rubolini D, Romano M, Boncoraglio G

Abstract excerpt

The length ratio between individual digits differs between males and females in humans, other mammals, lizards, and one bird species. Sexual dimorphism in digit ratios and variation among individuals of the same sex may depend on differential exposure to androgens and estrogens during embryonic life. Organizational effects of sex hormones could cause the observed correlations between digit ratios and diverse...
