Figure 9-12 shows the evolutionary history of the globin gene family members. Figure 9-12
Given this information, which of the following statements is TRUE?

A)The ancestral globin gene arose 500 million years ago.
B)The α-globin gene is more closely related to the ε-globin gene than to the δ-globin gene.
C)The nucleotide sequences of the two γ-globins will be most similar because they are the closest together on the chromosome.
D)The fetal β-globins arose from a gene duplication that occurred 200 million years ago, which gave rise to a β-globin expressed in the fetus and a β-globin expressed in the adult.
