Retracted: Experimental evidence that maternal corticosterone controls adaptive offspring sex ratios

Pryke, Sarah; Rollins, Lee A.; Griffith, Simon C; Buttemer, William A


Sex allocation theory has received considerable attention, yet the mechanism(s) by which mothers skew offspring sex ratios remain unknown. In birds, females are the heterogametic sex, which potentially gives them control of whether gametes will be male or female. How females might control the sex of the gamete is unclear, but one possibility is that variation in steroid hormones may mediate this process. We experimentally altered circulating levels of corticosterone in female Gouldian finches...[Show more]
