What is an example of an X-linked trait?
There are several examples of X-linked traits. These all behave in men like dominant traits because there is no gene on the Y chromosome to counteract the genes on the X chromosome. Examples: Hemophilia, male pattern baldness, and red-green color blindness are three examples. Keep in mind that if a female inherits one of these genes from her father and one of a similar gene from her mother, then she can display these normally male-only traits. Hemophilia is usually fatal to young women at or before puberty. Many post-menopausal women can be seen to have male pattern baldness.
Is baldness a sex-limited or a sex linked trait?
men with higher testastorone are more likely to go bald
How many genotypes are possible in a pedigree of sex linked traits?
xx = normal female x- x = carrier female x- x- = female which has the sex-linked trait xy = normal male x- y = male which has the sex-linked trait
What is the a pattern of inheritance in which certain characteristics carried on the X chromosome inherited from the mother are transmitted differently to her male and female offspring called?
Sex linked.
What Traits controlled by genes located on sex chromosomes are what kind of traits?
The Y chromosome controls sex because the SRY region( sex determining region ) is on this chromosome. XX is female as default. This is subject to some variation, as the SRY region sometimes ends up on an X chromosome and you have various chromosome distributions too. X, XXY, and the like. Other than that, there are too many traits that are under control of these chromosomes to list here.
Why is pattern baldness more common in men than in women?
pattern baldness is an X-linked recessive gene. Since men only have one X chromosome (XY) and females have two X chromosomes (XX) it is easier for men to no posses the dominant trait that prevents pattern baldness.

Why are boys more dominant in baldness than females?
The term dominant is a misnomer here as the trait is not dominant or the number of women with the trait would be much higher. Pattern baldness is a sex-linked trait. Male pattern baldness alleles are present on the X chromosome which means that only one copy of the allele is required for a male to exhibit the trait (the y chromosome, being much smaller, doesn't have the gene locus for this trait). Females must have 2 alleles for the characteristic in order to exhibit the the trait.

What is an example of a trait inside your body that is affected by your genes?
Male pattern baldness is a common genetic condition passed through the X chromosome that a man gets from his mother.
Male pattern baldness is a recessive sex-linked trait on the X chromosome Xb A woman whose father had male pattern baldness marries a man with this trait What is the probability that any son boor?
k so. i think you meant marries a woman? lol k so its recessive carried on the X chromosome. Her father genetic make up is X^b Y. marries a woman who has the trait is X^H X^h (since its recessive and dominant overthrows recessive and she has the trait h). so use a punnet square. you should get.. two girls. one is afflicted, the other one carries the trait. two boys: a normal son, and an afflicted son. Hope this helps!

Sex linked.
What are the sex-linked traits?
Sex linked-traits refer to any gene which appears on the X or Y chromosome, so they can be specifically tracked through generations along with the specific X or Y. A great example of this is baldness, which occurs on the X chromosome. Oddly enough this is the female chromosome, but as females get two, the chances of two baldness genes is very low. In any case it generally only shows up as a thining of hair late in life. However, in a male the gene is alone and has a major effect (complete or partial baldness). Because a man must give his Y to his sons, a bald father does not make a bald son. However a bald maternal grandfather can make a bald son (the gene came from grandpa, through mom to son with a 50/50 chance). There are several other sex-linked traits, but they all follow this pattern. They include things like hemophelia and colorblindness.
Why can women be a sex-linked genetic disorder but a male cannot?
Women can carry or have a sex linked (x-linked) genetic disorder. Males cannot be carriers, they either have the disorder or they don't: this is because the male has only one X chromosome.
