Bezzdna [24]

In humans, the embryonic and the fetal forms of haemoglobin have a higher affinity for oxygen than that of adults this is because non-identical genes produce different versions of globin during development. So the correct option is A.

<h3>What is meant by oxygen affinity? </h3><h3> </h3>

The amount of oxygen delivered to the cells will depend on the haemoglobin's oxygen affinity.  

Oxygen affinity is defined as the relationship between the saturation of haemoglobin oxygen, represented by SaO2 and the oxygen tension, represented by PaO2. This relationship is plotted by a dissociation curve which is S-shaped.  

Thus, in the embryonic the fetal form, haemoglobin has a higher affinity for oxygen.

Therefore the correct option is A.
