Sex linkage
- Human sex is determined by a pair of sex chromosomes
called X and Y. Because these chromosomes do not look
alike, they are sometimes referred to as heterzygous.
- X-linkage; sex linkage results in an inheritance pattern of different from that
shown by genes carried on autosomes. In x-linkage, a recessive allele is
expressed more often in males than in females because males carry only one
allele for an X-linked gene, whereas females have two alleles for the gene
