A double-strand break in genomic DNA that remains unrepaired can be lethal for a cell. Indeed, the integrity of the genome is paramount for survival. It is therefore surprising that some cells deliberately introduce double-strand breaks at certain times during their life cycle. Why might they do this? What are the benefits? How are these breaks repaired? The answers to these questions lie in understanding the basis of meiotic recombination, the process that leads to genetic variation. This
