Explanation:

In a recessive X linked disorder, a woman is said be be affected if she has both the recessive alleles on X chromosome. If she has one recessive allele then she is a carrier of the disease but she is herself normal. If she has both the dominant alleles, she is considered as absolutely normal. A carrier appears normal but she has an allele which is mutated and her progeny may be affected by the disease if her husband is not normal. It happens because females have XX chromosomes as allosomes.

In contrast to this, a male is affected by the disease even if he has one mutated/recessive allele because a male has only one X chromosome and another chromosome is Y in the allosome pair (XY chromosome). There is no other X chromosome in males which can suppress the recessive allele on the X chromosome and Y does not have any allele for this trait at all.
