Q2. Sickle-cell anaemia is an autosomal recessive genetic disorder that causes red blood cells to change shape, which can cause the red blood cells to become stuck in blood vessels. The allele that codes for normal red blood cells is represented with B whilst the recessive allele for sickle-cell anaemia is represented by b.

a)What are the possible genotypes for these alleles and the resulting phenotypes?

3

b) An man with sickle cell anaemia had a child with a woman who was heterozygous for normal red blood cells. Using a punnet square show the expected ratios for their children.
