Solutions For An Introduction to Genetic Analysis Chapter 17 Problem 8P

In the above figure we see a difference in the inversion products formed by breakage and by crossing over.

In breakage, we see that the process of inversion results in a gene with the sequence of 1-2-3-4.In crossing over, we see that the process of inversion results in a gene with the sequence of 1-3-2-4.

Here, we see that the gene sequence has been changed by the process of inversion in crossing over. The gene sequence is left unaltered in breakage.
