Finding: The overall degree of divergence between two homologous exons in related genes corresponds to the differences between the polypeptides.
Reason: Overall degree of divergence between two homologous exons is mostly a result of base substitutions.

A. In homologous introns, the pattern of divergence involves both changes in length.
B. Divergence in introns is due to deletions and insertions and base substitutions.
C. Introns are slowly evolve while exons much more rapidly
D. When a gene is compared among different species, there are instances where its exons are homologous but its introns have diverged so much that very little homology is retained.
