Is pattern baldness a sex-linked trait or a sex influenced trait?

men with higher testastorone are more likely to go bald


What gender is most likely to receive a sex-linked trait and why?

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.


Why are male more likely to receive a sex-linked trait?

because of unopposed alliles on y chromosome


Why are sex linked traits more common in males than in females?

Because males have only one X chromosome, males are more likely than females to have a sex-linked trait that is controlled by a recessive allele for a trait and one dominant.


Are males or females more likely to have colorblindness?

Males are more likely to get it. i do believe it's an x-linked recessive trait and that females are carriers and do pass it more to their son than to a daughter.


Why are males more likely than females to have a sex-linked trait that is recessive?

Because they olny have one X chromosome.


A dominant x linked trait would be more common in males or females?

the best answer would be that the X linked trait would be more common in females then males


What type of trait is hemophilia?

recessive sex-linked, X chromosome disorders, haemophilia is more likely to occur in males than females.


How does linkage affect the inheritance of traits?

As in sex linkage?Well if a trait is sex linked then one gender may be more likely to have that trait than the other. For example, colour blindness is a trait that is linked to the X chromosome. So males are more likely to be colour blind than females because the colour blindness gene is recessive and males only have 1 X chromosome where as females have 2 X chromosomes. Though females may be carriers of the colour blindness chromosome, therefore potentially passing it on to their children (son or daughter).


What are 2 human sex linked disorders?

Two human sex-linked disorders are hemophilia and color-blindness. These disorders are more likely to affect males.


Why are males momre likely than females to have sex-linked traits controlled by a recessive allele?

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.

Thus, males are more likely than females to have sex-linked traits controlled by a recessive allele.

What is the term when two or more genes affect an expression of a trait?

The type of heredity in which two or more genes affect an expression of a trait is called polygenic inheritance.


What type of trait is linked to the X chromosome sex linked trait or Mendelian trait?

The "X" and "Y" chromosomes carry traits that define gender. So any gene on these chromosomes may affect gender; these are called "sex-linked", or more properly, "gender-linked". An animal (and remember, humans are animals) cell that has two "X" chromosomes is female, while a cell with one "X" and one "Y" chromosome is male. The other chromosomes can be found in either male or female organisms.


Which sex usually inherits a sex-linked trait more frequently?

Men.


What is X-linked and Y-linked inheritance?

These are traits that are linked to the sex chromosomes. Only males can get Y-linked traits because only males have a Y chromosome. (Note: it's a bit more complicated that even this explanatin, but this is the general idea) If the father has the X-linked trait he can only pass it down to daughters. If the mother has the trait, the daughter might not have the trait because the father's donated X-chromosome might have a gene that masks it. If a son gets donated an X-chromosome from the mother with the trait, he will definitely show the trait.


When two or more sets of alleles affect the same trait in an additive fashion the trait is termed?

codominant


Are sex linked traits more or less likely to show up in males?

More likely in males.


What sex is more likely to inherit a sex linked trait?

Males, because while females have a duplicate of EVERY chromosome in their cells, in males the two sex chromosomes are different and therefore not duplicates.


What type of traits are there?

There are two traits dominate (which is more likely to appear because there are more genes towards the dominate trait and there is a weaker trait which is called recessive which can happen but is rare and not likely.


Why are sex linked traits observed more in males?

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.


A trait that can only be inherited by a male would be a?

Y-linked (sex-linked) - it would only be found on the Y chromosome - and therefore it is impossible for a female to inherit this.X-linked recessive traits are much more likely to occur in males, but it is still possible for a female to have them (if they have a defective gene on both their X chromosomes).


Are males or females more likely to have a sex-linked trait that is controlled by a recessive male?

If the trait is recessive and on the male chromosome (Y), then it is impossible for females to get it since they do not possess a Y chromosome. If you meant a recessive sex-linked trait on the X chromosome (like male pattern baldness), then males are still more likely to get it since they only receive one X chromosome and if it is affected they would automatically have the trait (whereas females have 2 copies and would only have the trait if both parents passed on chromosomes containing the recessive allele.) Females can be carriers, though. If they are a carrier (have one affected X chromosome) for the trait then their male children would have a 50% chance of inheriting the trait and their female children would have a 50% chance of becoming carriers.


Why do recessive phenotypes in sex-linked traits show up in males significantly more than in females?

Because males only have one X chromosome-sex linked traits are linked on the X chromosome. If they receive a recessive trait on the X chromosome, they automatically have the trait, and in females, they must have two X chromosomes for the given trait.


Why are males more likely than females to have sex-linked trait that is recessive?

a male's chromosomes are XY, whereas a girls are XX. With a female, hes sex-linked traits can be dominated by her other X chromosome. Whereas with boys, their Y is what they get, there's no changing it.
