WebWhen a gene is present on the X chromosome, but not on the Y chromosome, it is said to be X-linked. X-linked genes have different inheritance patterns than genes on non-sex chromosomes (autosomes). That's because these genes are present in different copy numbers in males and females. WebWhen the SRY gene is present, it is usually located on an X chromosome due to recombination between the X and Y chromosomes. However, translocation to an autosome can occur.
