Genes that are found on sex chromosomes are called sex-linked genes. These genes can be on either the x chromosome or the y chromosome. If a gene is located on the y chromosome, it is a y-linked gene. These genes are only inherited by males because, in most instances, males have a genotype of (xy). Sex linked genes are genes that are in the sex chromosomes and that are therefore inherited differently between males and females. Com, a free online dictionary with pronunciation, synonyms and translation. Sex-linked diseases are passed down through families through one of the x or y chromosomes. Dominant inheritance occurs when an abnormal gene from one parent causes disease, even though the matching gene from the other parent is normal. X-linked gene a gene carried on the x chromosome the corresponding trait, whether dominant or recessive, is always expressed in males, who have only one x chromosome.

These not only carry the genes that determine male and female traits but also those for some other characteristics as well. Genes that are carried by either sex chromosome are said to be sex linked. Sex linked is a trait in which a gene is located on a sex chromosome. In humans, the term generally refers to traits that are influenced by genes on the x chromosome. This is because the x chromosome is large and contains many more genes than the smaller y chromosome.   sex-linked character, observable feature of an organism controlled by genes on the sex chromosomes. In humans, the x (female) chromosome carries many genes, whereas the y (male) chromosome is deficient in genes. Red-green color blindness and hemophilia are examples of sex-linked traits in humans.
