Answer :

 is a genetic disorder in which blood fails to clot.

Answer:

The correct answer would be X-linked recessive disorder.

It is an X-linked recessive disorder due to which it is more common in males as compared to females.

Males carry only one X chromosome due to which presence of the single mutant allele is enough to produce the phenotype.

In contrast, the females carry two X chromosomes due to which they require two copies of mutated allele. Thus, the chances of a female to express a disease is less.
