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.
Are sex-linked traits that are recessive phenotypes most often seen in men or woman?
men
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.
Which statement best predicts the results of the cross MmDdPp x mmddpp assuming that all three genes are linked?
All eight possible phenotypes could occur, but a greater proportion of the offspring would have the parental phenotypes.

men
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
What are the probable mode of inheritance from a pedigree diagram showing phenotypes?
The modes of inheritance are y-linked, x-linked, and mitochondrial. Inherited traits can then be recessive, dominant, or autosomal depending on how they are inherited.
Which statement best predicts the results of the cross MmDdPp x mmddpp assuming that all three genes are linked?
All eight possible phenotypes could occur, but a greater proportion of the offspring would have the parental phenotypes.
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.
