Autosomal genes | All other genes except for sex-linked genes |
Sex-linked genes | Genes located on the sex chromosomes |
In mammals, the sex chromosomes are designated…? Females? Males? | X & Y; Females= two X chromosomes (XX); Males= an X & Y chromosome (XY) |
During reproduction females contribute an..? Males?.. That determines..? | Females contribute an X chromosome; Males contribute either an X or a Y chromosome that determines the sex of the child |
