Answer:

The gene mutation that inserts an extra base pair into the genetic sequence would cause the most dramatic change in the genetic make-up of and individual.

Explanation:

This is because the insertion of an extra base pair shifts the 3 base-pair sequences for amino acids. Each amino acid sequence after the the insertion has been changed. This means that each amino acid sequence codes for a different amino acid than originally intended, so the development of this person could be severely inhibited by their lack of the proper proteins.

B a gene mutation that inserts one extra base pair
