Normally sex-linked traits are carried only on the X chromosome, meaning a sex-linked gene can only be inherited from the father's X or the two mother's X's. However, there are occasions where the trait is carried down by the Y chromosome, meaning only the males would inherit it, and it would be expressed. This is very uncommon because the Y chromosome carries very little genetic material/information in comparison to the Y chromosome.

Boys can inherit an X-linked trait from their?
Father
Since the colorblindness is located on the X chromosome colorblindness?
Why is colorblindness a sex-linked trait? Descendants of colorblind hemophiliac man both disease are sex- linked? why do non of the children have either hemophila or colorblind
What is a trait that is passed from parent to child on the X chromosome called?
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.
What is an X linked traits?
An X-linked recessive trait is coded for by a gene on the X-chromosome and is not dominant (is canceled out by the presence of a different allele). Example of X-linked recessive traits are; Haemophilia A & B and Duchenne muscular dystrophy.
Is color blind dominant or recessive?
recessive
When the trait is on the X-chromosomes what is it called?
It is a sex-linked trait. Genes only found on the X chromosome can result in sex-linked traits. In humans these include hemophilia and color blindness.
What is the defineion to sex linked trait?
A sex linked trait is from a gene that is on either the x or y chromosomes
Is breast cancer a X-linked trait?

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 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.
Is an x linked dominant trait the same as an x linked recessive gene?
An X-linked recessive trait is coded for by a gene on the X-chromosome and is not dominant (is canceled out by the presence of a different allele). Example of X-linked recessive traits are; Haemophilia A & B and Duchenne muscular dystrophy.
How does the inheritence of X linked traits differ from that of other traits?
X-linked traits are transferred from parents, or a parentto their offspring on the X Chromosome. That is the biggest difference--as opposed to being located on any chromosome, X-linked traits are only transferred on X Chromosomes. A common X-linked trait is actually colorblindness. Often, X-linked traits or disorders are recessive; since men have only one X chromosome (because they are XY), they are often more prone to X-linked disorders, whereas women, who have two X chromosomes, often become "carriers"--that is, they have one X chromosome with a certain trait, but the other X chromosome has a dominant trait that masks the manifestation of the other trait.
What is the opposite of independent assortment?
Linked gene inheritance. In humans, it is called x-linked inheritance; sex-linked inheritance is when the trait is carried on the X chromosome.
What is an recessive trait?
An X-linked recessive trait is coded for by a gene on the X-chromosome and is not dominant (is canceled out by the presence of a different allele). Example of X-linked recessive traits are; Haemophilia A & B and Duchenne muscular dystrophy.
