It's more common to happen transitions (even though there are less possibilities) because of the shape of the molecules.

Transitions exchange bases of similar shape (swaps a purine for a purine or a pyrimidine for a pyrimidine), whereas transversions exchange bases of different shape (swaps a purine for a pyrimidine (or vice versa)).

A and G are purines, C and T are pyrimidines.

possible transversions A-C, A-T, T-G, G-C

transitions are A-G or C-T

answer: AG or CT pairs
