Further proof that mammalian intercourse ratios at delivery are partially managed by parental hormones
The note that is present an effort to supplement past argument regarding the hypothesized parental hormonal antecedents of mammalian offspring sex ratios. Its meant that a reader that has read both this paper and my paper that is previous should aware of the many data concerning the hypothesis James WH (1996), J Theor Biol 180, 271–286.
It’s been hypothesized that the sexes of offspring of mammalian (including individual) parents are causally regarding the hormones levels of both moms and dads across the time of conception.
