One disorder could be colorblindness. Colorblindness is most common in males because in order to have to disorder you must carry two mutated X chromosomes. Another recessive genetic disorder you can get is called Hemophilia. This is a disorder in which the genes for hemoglobin are not present and your body is not able to create blood clots and a simple scratch can be very serious.
X-linked traits are rare in females because they have two X chromosomes, which allows for compensation of any defective genes on one X chromosome with the normal genes on the other X chromosome. In contrast, males only have one X chromosome, so any defective gene on that chromosome will be expressed. This is why X-linked traits are more commonly observed in males.
Males are generally more susceptible to sex-linked diseases, particularly those linked to the X chromosome, such as hemophilia and color blindness. This is because males have one X and one Y chromosome (XY), so any recessive allele on the X chromosome will express the disease. In contrast, females have two X chromosomes (XX), which provides a protective effect; if one X carries a recessive disease allele, the other X can often compensate. Consequently, females may be carriers without exhibiting symptoms, while males are more likely to be affected.
sex-linked disorders
The best known examples in humans are color-blindness and muscular dystrophy. Males are the ones that are the most vulnerable because the Y chromosome is shorter than the X chromosomes that females have.
A Y-linked gene is a gene that is carried on the Y chromosome, a sex chromosome found only in male cells. In humans, the most commonly mentioned Y-linked gene encodes a protein called testis-determining factor (TDF). As the name suggests, TDF prompts the development of the testes. Since only genetic males have a Y chromosome, only males express TDF and go on to develop testes. In general, genes carried on the sex chromosomes (X and Y) are considered to be "linked" to that chromosome. Genes carried on the X chromosome are considered X-linked in the same way that TDF is considered Y-linked.
Sex-linked disorders are inherited through genes located on the sex chromosomes (X and Y). Diseases on the X chromosome are more common because males have only one X chromosome, making them more susceptible to X-linked disorders. Females have two X chromosomes, offering a protective factor where a mutation on one X chromosome may be compensated by the other. Y-linked disorders are rare and only affect males since females do not have a Y chromosome.
Most sex-linked traits are found on the X chromosome because males have only one X chromosome, so any gene on the X chromosome will be expressed in males. In females, who have two X chromosomes, one X chromosome can compensate for any harmful gene on the other X chromosome.
X-linked refers to a gene carried on the X chromosome, one of the two sex chromosomes.

Odds favor X-linked diseases because everyone has a least one X chromosome as opposed to a Y which only 50% (males) have. Since women have two Xs, they are less affected by X-linked diseases too, because they have likely inherited one perfect X from one parent and one damaged X from the other, where a man only has one X from his mom so if it's damaged he's going to have the disease expressed when his sister might not or have a milder version of the same disorder.
No, not all sex-linked traits are located on the X chromosome. Some sex-linked traits can also be located on the Y chromosome.
sex-linked disorders
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.

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.
