sex linkage
the location of genes on one or other of the SEX CHROMOSOMES producing an inheritance pattern which is different from that shown by AUTOSOMES. See Fig. 283 .Most sex-linked genes are located on the X-chromosome (X-linkage), although some conditions are controlled by genes on the Y-chromosome (Y-linkage) that are only transmitted through the males, for example, genes responsible for SEX DETERMINATION in mammals.
