78Fetal hemoglobin has a higher affinity for O 2 than adult hemoglobin. This is due to

Fetal hemoglobin has a decreased ability to bind to 2,3-bisphosphoglycerate (BPG) compared to adult hemoglobin. This allows fetal hemoglobin to have a higher affinity for oxygen, which is important for oxygen transfer across the placenta from the maternal bloodstream.
