Refer to figure.
A researcher compares the sequences of a specific gene from various primate species.At nucleotide position 687 of this gene, all but two of the primates have a cytosine: the human has adenine, and the lemur has guanine at this position.This is evidence that the nucleotide substitutions at position 687 in humans and chimpanzees are most likely an example of
A) a transversion.
B) reversion.
C) multiple substitutions.
D) coincident substitutions.
