The genetics of sex-ratio variation have important implications for the evolution of the sex ratio for two reasons. First, additive genetic variance is required for the evolution of any trait, ...
Biostatisticians have developed a new estimation method for assessing natural variations in the sex ratio at birth (SRB) for all countries in the world. An international team of researchers, led by ...
Ray and colleagues1 present data on variation in birth sex ratios among Ontario newborns, showing a significant male-biased sex ratio at birth among multiparous Indian and South Korean mothers. The ...
