Question

Differentiate between complete sex-linkage and incomplete sex linkage with reference to location of the gene and inheritance.

Answer 1

Factors	Complete sex-linkage	Incomplete sex-linkage
Location:	The gene is located on the non-homologous region of the X chromosome (or Y chromosome).	The gene is located on the homologous region (pairing segment) of the X and Y chromosomes.
Inheritance:	Such genes are inherited along with the sex chromosome and are not transmitted from father to son (as with X-linked genes).	These genes exhibit inheritance patterns similar to those of autosomal genes because they can be transmitted through both the X and Y chromosomes.
