Question

Which of the following is the most well-known example of incomplete dominance?
A) Cystic fibrosis
B) Hemophilia
C) Obesity
D) Sickle-cell anemia
E) Duchenne's muscular dystrophy

Accepted Answer

Sickle-cell anemia is a classic example of incomplete dominance, where the heterozygous genotype results in a condition that is not as severe as the homozygous recessive genotype, leading to sickle-shaped red blood cells that can still function to some extent, unlike the more severe symptoms seen in individuals with two copies of the sickle-cell gene.
