Baldness is not a sex-limited trait because both men and women can experience it. It is considered a sex-influenced trait because it is influenced by sex hormones but not exclusively linked to a specific sex chromosome.
No, an X-linked dominant trait is a gene located on the X chromosome that only requires one copy to be expressed, while an X-linked recessive gene requires two copies for expression. X-linked dominant traits are more likely to be expressed in females, while X-linked recessive traits are more commonly seen in males.
Sex-linked traits are more likely to show up in males because they are located on the X chromosome. Males only have one X chromosome, so a recessive allele on the X chromosome will be expressed, whereas females have two X chromosomes and would need to inherit two recessive alleles to express the trait.
Sex-linked traits are typically associated with the X or Y chromosome. In humans, these traits are commonly linked to the X chromosome, and therefore individuals with two X chromosomes (females) are more commonly affected by sex-linked traits, as they have a second X chromosome that may carry the allele for the trait. Males, with only one X chromosome, are more prone to expressing X-linked traits passed down from their mother.
Color blindness is an example of a trait that is inherited on sex chromosomes. It is passed down on the X chromosome, and males are more likely to be colorblind because they have only one X chromosome.
Because they olny have one X chromosome.
Males are more likely than females to have sex-linked traits controlled by a recessive allele because they only need one recessive allele to have the sex-linked trait. In contrast, females need two recessive alleles to have the sex-linked trait, so they have a lower probability of having it.This is best viewed with a Punnet square. Say the recessive allele that controls the sex-linked trait is Xa. XA is the dominant allele and Y is the male chromosome.Scenario #1If the mom is XA XA and marries a man with the sex-linked trait Xa Y, then none of the sons will have the sex-linked trait. All the daughters will have the mutant allele, but they will all be carriers with normal phenotypes since they only have one mutant allele.XaYXAXA XaXa YXAXA XaXa YScenario #2If the mom is XA Xa and marries a man with the sex-linked trait Xa Y, then there is a 50% chance that each child will have the sex-linked trait, regardless of sex.XaYXAXA XaXA YXaXa XaXa YScenario #3If the mom is a carrier XA Xa and marries a normal man XA Y, then there is a 50% chance each son will have the sex-linked trait. The daughters may be carriers, but none of them will have the sex-linked trait.XAYXAXA XAXA YXaXA XaXa YScenario #4If the mom has the sex-linked trait Xa Xa and marries a normal man XA Y, then all of the sons will have the sex-linked trait. The daughters will be carriers, but none of them will have the sex-linked trait.XAYXaXA XaXa YXaXA XaXa YScenario #5If the mom has the sex-linked trait Xa Xa and marries a man who also has the sex-linked trait Xa Y, then all of their children will have the sex-linked trait.XaYXaXa XaXa YXaXa XaXa YAs you can see, there are many more strikethrough outcomes (8) where the male has the sex-linked trait controlled by a recessive allele than bold outcomes (3) where the female has the sex-linked trait. Thus, males are more likely than females to have sex-linked traits controlled by a recessive allele.
recessive sex-linked, X chromosome disorders, haemophilia is more likely to occur in males than females.

A trait is sex-linked dominant if it appears in every generation and affects both males and females. It is sex-linked recessive if it skips generations, more common in males, and passed from carrier females to affected males. Mendelian inheritance patterns can help determine if a trait is sex-linked dominant or sex-linked recessive.
No, an X-linked dominant trait is a gene located on the X chromosome that only requires one copy to be expressed, while an X-linked recessive gene requires two copies for expression. X-linked dominant traits are more likely to be expressed in females, while X-linked recessive traits are more commonly seen in males.
Recessive traits on X chromosome are expressed in males because they have only one copy of X chromosome. If they have any recessive gene it will be expressed. In female both the genes should be recessive then only the recessive character will be expressed.

XX = Female XY = Male If there is a sex linked trait and it is recessive and will generally be on the X chromosome the statistical analysis will show that men will express this trait more often since they have only one X chromosome.
