Answer:
The correct answer is codominance.
Explanation:
It is given in the question that the genotype of Martin is HbS/HbS, and is exhibiting sickle cell anemia with unusual hemoglobin. On the other hand, the genotype of Cindy is HbA/HbA, which shows that she possesses normal hemoglobin. Both of them have a child, Mary who as usual is exhibiting genotype HbS/HbA.
This shows that Mary has acquired both the alleles for sickle cell anemia from her parents, and thus, is demonstrating both unusual and normal form of hemoglobin. Sickle cell is a condition that does not demonstrate the phenomenon of complete dominance, as it is a codominant trait.
A phenomenon in which the features of both the alleles are expressed in the phenotype is termed as codominance. Hence, Mary is demonstrating a codominance pattern.
