Hemophilia Inheritance Pattern: Father Affected, Mother Not a Carrier #133284 (License: Personal Use)

This genetic diagram illustrates X-linked recessive inheritance of hemophilia: an affected father (X^hY) passes his mutated X chromosome to all daughters (making them carriers, X^hX), while sons inherit his Y chromosome and a normal X from the mother, remaining unaffected (XY). The mother’s genotype (XX, non-carrier) ensures no additional mutation is introduced. This pattern contrasts with cases where the mother is a carrier or affected.

Used in medical education, genetics resources, and patient counseling pages to explain inheritance risks; targets users seeking to understand familial hemophilia transmission, especially when only the father is affected.
