Males only have one copy of the X chromosome
Sex-linked recessive conditions are more likely to occur in males because they only need to inherit one copy of the affected gene in order to exhibit the condition (as they have one X chromosome). Females, on the other hand, have two X chromosomes, so they need to inherit two copies of the affected gene to exhibit the condition.

By observing the proportion of affected offspring and whether males or females are more affected.
males have only one X chromosomes
Males are generally affected more.
Sex-linked.
Males have only one X chromosome. This means that only one copy of the sex-linked trait has to be passed toa male inorder for him to have the trait. If the mother is a carrier her male offspring have a 50% chance of inheriting and having the affected phenotype. Her daughters, will have a 50% chance of being carriers of the trait and could only be affected if the father is affected,
Males only have one copy of the X chromosome
Although males comprise only about 1/10 of all people with anorexia, when they do have anorexia they are affected as severely as are women with the same illness. Males are affected by anorexia in the same way as women are: for example, they can have organ failure, extreme emaciation, and even death. However, males with anorexia may not be taken as seriously as women because anorexia is often viewed as a women's disease.
No, Fragile X is on the X chromosome. Females have 2 X chromosomes and Males have an X and a Y Chromosome. Therefore, both males and females can have Fragile X (they can have the full mutation or be carriers). Males are usually more severly affected because they have only one X Chromosome.
what races and gender are affected the most and with which type of cancer
Hemophilia is an X-linked recessive disease which means the disease can manifest only if the genes on both chromosomes are affected. As males have only one X chromosome the disease always manifests. It is possible for a female to be affected but it is very rare.
Males can't catch PID.
