Among the ice fishes,Neopagetopsis ionah had white blood,but intact alpha and beta globin genes.Why was their blood still white?

Question

Quizplus · Accepted Answer

The intact alpha and beta globin genes suggest that the fish should have been able to produce hemoglobin, but the fact that their blood is white indicates that something went wrong in the process of producing functional hemoglobin. A likely explanation is that the genes were mutated in a way that prevents proper folding or assembly of the protein, leading to its degradation or accumulation in unusable forms.
