Which of the following is true regarding fetal hemoglobin?
- It is present until about 2 - 4 months after birth.
- It replaces the α sub units with γ sub units.
- It binds 2,3 BPG tightly.
- It has a greater affinity for oxygen than myoglobin.
- Fetal hemoglobin is mostly in the T-state.
Fetal hemoglobin is composed of which of the following?
- Two alpha and two gamma sub units
- Two alpha and two beta sub units

- Two beta and two delta sub units
- Two alpha and two delta sub units
Which statement is NOT true regarding fetal hemoglobin?

- Fetal hemoglobin always stays in a relaxed state, hence it is capable of uptake of oxygen at a rapid rate from the maternal blood.
- Fetal hemoglobin does not bind with 2,3-bisphosphoglycerate.
- Fetal hemoglobin releases oxygen more readily than myoglobin, but to a lesser extent than adult hemoglobin
- The oxygen affinity, in order, is myoglobin > fetal HB > adult HB.
