5.4 Sex-linked recessive inheritance

Preceding page

Sex-linked inheritance works differently in mammals than in birds. In mammals the sex-chromosomes are called XX and XY in female and male, respectively. In the birds the female is the hetero gametic, WZ, and the male is homo gametic, ZZ. The sex of the offspring is determined by the hetero gametic sex, in birds by the female and in mammals by the male.
