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.
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

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.
No, hitchhiker's thumb is not an X-linked trait; it is a result of a genetic variation that is considered to be an autosomal trait. This means it can be inherited from either parent, regardless of the sex of the offspring. The trait is associated with the flexibility of the thumb joint, and its inheritance pattern follows a simple Mendelian trait pattern rather than being linked to the sex chromosomes.
Diabetes is not an X-linked trait. It is a complex condition that can be influenced by a combination of genetic and environmental factors, rather than being specifically linked to genes on the X chromosome.
When a trait is located on the X chromosome, it is referred to as an X-linked trait. This means the trait is inherited through the X chromosome and can show different patterns of inheritance compared to traits on autosomes. Examples of X-linked traits include red-green color blindness and hemophilia.
A sex linked trait is from a gene that is on either the x or y chromosomes

Yes.
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.

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.
