They can, including hemophilia, which is almost always fatal for them. Its just much rarer since the Y chromosome is best thought of as a crippled X.
Sex-linked means it is transmetted to children by only one parent -- usually carried by the female but exhibited by the male children. Male pattern baldness is such a sex-linked trait. This answer is not complete, but to go further would require I explain chromosomes
It means genes are in sex chromosomes. Sex genes are related
Genes passed to offspring that code for a particular trait are not linked to different genes which code for different traits. ie. The gene for brown eyes assorts independently to the offspring and would not be effected by the gene coding for the trait of brown hair, for example.
The principle of excessiveness is defined as the explanation of why one trait will not show over another. If a trait is recessive it will not show when a dominant trait is present.
If an individual in a pedigree is labeled with R, it typically signifies that this individual has been identified as a carrier of a specific genetic variant or trait within the family. The “R” designation may stand for “resistant” in the context of that particular genetic trait or could be used for other notations depending on the specific pedigree and research context.
A carrier is an organism that inherits a specific genetic trait but does not show the trait in their phenotype, or physical appearance.
Sex-linked means it is transmetted to children by only one parent -- usually carried by the female but exhibited by the male children. Male pattern baldness is such a sex-linked trait. This answer is not complete, but to go further would require I explain chromosomes
If gene controling a character is located on sex chromosome , it is said to be sex linked .
In sex-linked traits, slashes are used to designate the sex of an individual and the genotype for a specific trait. For example, in females with two X chromosomes and a recessive allele for a trait, the genotype would be represented as X^bX^b (affected) or X^BX^b (carrier). In males, the genotype is represented with just one X chromosome, as in X^bY (affected) or X^BY (unaffected).
Generally the trait is on the X chromosome, as the Y is rather small and full of deleterious mutations and has few working genes. But and trait that is located on a sex chromosome is said to be sex linked. Naturally, women have two, XX, chromosomes, so ore protected statistically from many sex linked recessive disorders.

carrier--- if someone has part of a disease in their genetics but does not have the diseas themself eg. rets syndrome. It's also the person who is heterozygous for the trait, or disease. Ex: Mn, Jj, Kk, Ll, Tt, ect..
To be "x-linked" means that a trait is carried on the X-Chromosome. Recall that each child receives one chromosome from each parent, a male receiving one X and one Y -chromosome, and a female receiving two X -chromosomes. Because the male receives only one X-chromosome, he only need receive one X with a particular trait to be affected, whereas the female would need two Xs with traits to be affected. So, Asperger's Syndrome is more prevalent among males, as they only need receive one X-chromosome with Asberger's on it. This Asperger's-X must be from the mother, as the father would give the Y-chromosome required for a male. Since the mother has two X-chromosomes that might be affected (depending on if she has the Syndrome, or is just a carrier), there is a 75% chance the male will have Asperger's Syndrome if the mother has at least one Asperger's-X. Conversely, a female must have one Asperger's-X from each parent, so if the mother has two Asperger's-X -chromosomes, the daughter will still only be a carrier (and so not have Asperger's Syndrome), if the father also carries the trait on his X-chromosome.
yes. One time six states had estimated how much of the population had hemophilia, and got about 7,000. There isn't a actual known amount of people that actually have Hemophilia, but it is estimated about 20,000 people in America that DO have it. You inheritet it from parents, also known as the term called "sex-linked". Hope i helped:)

Males are more likely to receive a sex-linked genetic trait because they have only one X chromosome. A certain trait on a woman's X may be covered up by another trait on her other X, men only have one X so they are stuck with whatever trait appears on it.
