X-linked recessive inheritance is a mode of inheritance in which a mutation in a gene on the X chromosome causes the phenotype to be always expressed in males who are necessarily homozygous for the gene mutation because they have one X and one Y chromosome and in females who are homozygous for the gene mutation, see zygosity.

  • Feb 07,  · Traits are inherited from one generation to the next generation via our genes. When these genes are located on our sex chromosomes, the corresponding traits are known as sex-linked traits; Sex-linked genes are found on our sex chromosomes. These genes are either Y-linked if found on the Y chromosome or X-linked if found on the X chromosome. Sex-linked traits are associated with genes found on sex chromosomes (X and Y). As the female X-chromosome is larger, X-linked traits are more common than Y-linked traits. An example of a sex-linked trait is red-green colorblindness, which is carried on the X-chromosome.
