Question

If a haemophilic father (Xh Y) has children with a normal mother (XH XH), what will be the status of all daughters?

पर्याय

• All daughters will be normal

• All daughters will be carriers

• 50% daughters will be carriers

• All daughters will be affected

Answer 1

A haemophilic father (Xh Y) passes his X chromosome (Xh) to all his daughters. Since the mother is normal (XH XH), all daughters will have the genotype XH Xh, making them carriers. This is because daughters receive one X from their father and one from their mother.
