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.
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.
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.
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.
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

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.

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.
