Sex-Linked Traits

Sex-Linked Traits. Ch. 10.5. Sex-Linked Genes. Sex chromosomes: X and Y (male: XY, female: XX) Offspring sex depends on whether the sperm cell that fertilizes the egg carries an X or a Y Sex-linked gene = any gene that is located on a sex chromosome (most found on the X chromosome).
