Resource summary

Sex linkage
  1. 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.
    1. 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
