Which Type of Hemoglobin Contains 2 Alpha and 2 Gamma

Question

Which type of hemoglobin contains 2 alpha and 2 gamma chains?
A) HbF
B) HbM
C) HbS
D) HbO

Accepted Answer

HbF, or fetal hemoglobin, is composed of two alpha and two gamma chains, which is different from adult hemoglobin (HbA) that contains two alpha and two beta chains. This composition allows HbF to have a higher affinity for oxygen than adult hemoglobin, facilitating the transfer of oxygen from the mother to the fetus.
