Question

Sickle cell anaemia is

an autosomal-linked dominant trait

caused by substitution of valine by glutamic acid in the β-globin chain of haemoglobin

caused by a change in a base pair of DNA

characterised by elongated sickle-like RBCs with a nucleus

Solution

caused by a change in a base pair of DNA

Sickle-cell anaemia is caused by a change in a single base DNA. It is genetic disease reported from negroes. The individuals of stickle-cell anaemia are immune to malaria.
