title: Further evidence that mammalian sex ratios at birth are partially controlled by parental hormone levels around the time of conception.
abstract: The present note is an attempt to supplement previous argument on the hypothesized parental hormonal antecedents of mammalian offspring sex ratios. It is intended that a reader who has read both this paper and my previous paper should be aware of all the data relating to the hypothesis [James WH (1996), J Theor Biol 180, 271-286].
