摘要：

I examined the sex ratio of litters of mule deer (Odocoileus hemionus) collected during late winter in 1984-1989 in eastern California. Although the overall sex ratio was unity, heavier mothers, and those with higher kidney-fat indexes, tended to produce male-biased litters. Results conformed to predictions from theory that relates maternal-investment ability to adaptive variation in sex ratios of offspring in polygynous animals.
