3. Sickle cell anaemia – Autosomal recessive trait, chromosome-11

Solution:
✓ This is an autosome linked recessive trait.
✓ The disease is controlled by a single pair of allele, HbA and HbS.
✓That can be transmitted from parents to the offspring when both the partners are carrier for the gene (or heterozygous).
✓ Only the homozygous individuals for HbS (HbSHbS) show the diseased phenotype.
