Sex linkage refers to gene inheritances. Many animals have sex cells or gametes. These are often Designated to X and Y, which are key determining gender. The rest of the chromosomes are referred to as autosomes. Sex linkage inheritance and autosomal inheritance follow different patterns. XY males only have 1 copy of the X chromosome and are hemizygous for all genes on that chromosome, while females are either heterozygous or homozygous[1].
