Described how sex - linked are expressed differently in males and in females?

In humans, females (XX) have two X chromossomes whereas males only have one. While most of one of the X chromossomes is deactivated in females it's still less likely for females to get an X-linked genetic disorder unless in double dose or a dominante gene. For males (XY), on the other hand, since they only have one X chromossome that isn't deactivated, one dose is usually enough to cause them to have the disorder, whether the gene is recessive or dominant. That's why males are way more likely to get such disorders than females. Hemofilia, daltonism and baldness would be three examples.
Traits linked to the Y chromossome will practically always manifest in males, and never in females. Hairy ears would be one example.

Why is hemophilia rarely expressed in females?
Because hemophilia is a disease linked to a recessive gene on the X-chromosome, females have another X-chromosome to block out the diseased one. However, males have only one X-chromosome, so they are more often subject to hemophilia.
What is the most likely mode of transmission for a trait that is not expressed in parents but is expressed by one half of the sons?
Rare X-linked recessive
Why are sex-linked traits more conman in males?
Because males have XY configuration of sex chromosomes and females XX. So in xy situation even the recessive gene can express. That is why sex-linked characters in males are more common than females.

Why do x linked conditions appear more frequently in males than females?
Because males have an X and Y chromosome. If the trait is X-linked (recessive), there is nothing to mask the expression. On the other hand if a woman has an x-linked recessive allele and a dominant one, the dominant trait is the one that will be expressed.
Why is hemophilia rarely expressed in females?
Because hemophilia is a disease linked to a recessive gene on the X-chromosome, females have another X-chromosome to block out the diseased one. However, males have only one X-chromosome, so they are more often subject to hemophilia.
What do you call a disorder in which females are the only ones who can be carriers?
a sex-linked, or X-linked disorder
Why are x linked alleles expressed in males even if they are recessive?
X-linked are not recessive nor dominant. X-linked just do not show. On the sex-linked chromosomes the Y chromosome of the X-Y pair dominates the trait whether its recessive or dominant!Actually, all x-linked alleles are expressed because males only have one x-chromosome, so whatever is there, dominant or recessive, is expressed.
What is the most likely mode of transmission for a trait that is not expressed in parents but is expressed by one half of the sons?
Rare X-linked recessive
A gene that is sex-linked is BEST described as what?
It is located on the X chromosome.
How x linked traits affect the inheritance of sex linked traits?
Females have 2 X chromosomes so the X-linked genes follow the same rules of dominance & recessivity as the genes on the autosomes.
