So let's say this one right here and this one right here takes place. And that allows the exchange of genetic information in a process known as crossing over, and that produces genetically recombinant chromosomes. So basically, during ProPhase one of meiosis, these two homologous chromosomes that have been replicated basically approach one another. And now this right here can basically overlap with this right here. And when this interlapping or overlapping takes place, this is known as synapses. So we have this overlaps onto this right over here.
