Quizplus · Accepted Answer

The question is focused on the difference in hemoglobin affinity for oxygen during development in humans. This suggests that the answer involves a difference in the genes or gene expression during development. Choice A is the most directly related to this concept, as it suggests that nonidentical genes produce different versions of globins during development, which would explain the difference in hemoglobin affinity. The other choices are not directly related to this concept or are incorrect (such as pseudogenes interfering with gene expression in adults).
