Abstract
The two important questions that this paper will attempt to answer are: (1) why is it that regardless of race/ethnicity or geographic location, the sex ratio data at birth show more males than females?; and (2) Why is it that regardless of geographic location compared to other racial/ethnic groups, Black women or Women of sub-Saharan Black African descent tend to give birth to more females? Or to put this question the other way around, compared to Black women, why do non-Black women give birth to more males? (Afr J Reprod Health 2008; 12[3]:139-150).
RĖSUMĖ
Proportion sexuelle en accouchement et différences raciales: Pourquoi des femmes noires accouchent-elles de plus de filles que des femmes non-noires? Les deux questions pertinentes que cette communication essayera de répondre sont : (1) pourquoi les données de la proportion sexuelle à la naissance montre plus de filles que de garçons sans se soucier de la race/de l’ethnie ou du milieu géographique ? (2) Pourquoi les femmes noires ou des femmes descendues de l’Afrique noire subsaharienne tendent à accoucher plus de filles sans se soucier du milieu géographique par rapport aux autres groupes raciaux/ethniques ? Pour reformuler cette question ; pourquoi les femmes non colorées donnent naissance à plus de garçons par rapport aux femmes noires? (Afr J Reprod Health 2008; 12[3]:139-150).
