Because Hemophilia is Carried on the X Chromosome,women are Twice

Question

Because hemophilia is carried on the X chromosome,women are twice as likely to have it as men.

Accepted Answer

Women can only have hemophilia if they inherit two copies of the gene, one from each parent who carries it. Since men only have one X chromosome, they are more likely to be affected if they inherit the gene from their carrier mother. Women who only inherit one copy of the gene are carriers but typically do not have symptoms of the condition. Therefore, men are more likely to have hemophilia than women.
