Why an X-linked recessive disease can skip generations?

Question

Quizplus · Accepted Answer

Skipped generations are often observed in X-linked recessive disease pedigrees because the gene can be transmitted through female carriers. Males are hemizygous for genes on the X chromosome. Fathers cannot pass X-linked genes to their sons. X-linked recessive diseases are observed significantly more often in males than in females, because males need only one copy of the gene to express the disease.
