A gerbil dam's fetal intrauterine position affects the sex ratios of litters she gestates
Abstract
The vaginally delivered litters of gerbil dams that, in utero, occupied intrauterine positions between two males fetuses (2M females) contain a greater proportion of sons than do the vaginally delivered litters of gerbil dams that were gestated between two female fetuses (2F females). This difference in the sex ratios of litters delivered vaginally by 2M and 2F gerbils might reflect sex-biased differences in perinatal mortality in the litters …
