Colour blindness is a sex-linked recessive disease males are affected more often than females because the gene is located on x chromosomes.

Colour blindness is a defect in which a person cannot distinguish between re, green or both the colours from other colours.

Thalassemia is an autosomal recessive disorder. It is transmitted to the offspring when both the parents are heterogeneous or carriers of the disease.
