What do you mean by crossing over?
Crossing over is the exchange of genetic material between the non-sister chromatids of a homologous chromosome.
There are two chromosomes in the diagram i.e. light and dark-colored. In the third step, there is a process of crossing over occurring between the non-sister chromatids to produce a genetic variation, which results in a new allelic combination in the daughter cells.
Therefore, the diagram illustrates the process of crossing over.
