A woman may develop a recessive sex-linked defective genetic trait

Question

Quizplus · Accepted Answer

A woman can develop a recessive sex-linked defective genetic trait only when she is homozygous for the recessive trait. This is because the defective trait is located on the X chromosome, and females have two X chromosomes. If a woman has one normal X chromosome and one X chromosome with the defective gene, she will be a carrier of the trait but not affected by it. Only if she has two copies of the defective gene (homozygous) on both X chromosomes will she express the trait. Y chromosome does not have any impact on this scenario as women do not inherit Y chromosomes.
