What nucleotide change is a shared derived character for species A, B, and C, but not for species G?
Note: A,T,G, and C refer to nucleotide bases, and the numbers refer to the position of the base in the nucleotide sequences. For example, A6 refers to an adenine at the sixth position.
A. Changing the second G to an A is common to species A, B, and C, but not to species G.
B. Changing the fifth T to a G is common to species A, B, and C, but not to species G.
C. Changing the second G to a T is common to species A, B, and C, but not to species G.
D. Changing the second G to an A and the fifth T to a G is common to species A, B, and C, but not to species G.
E. None of these show a change in derived characteristics for A, B, and C that are not found in G.
