At the end, we formed the following pair of homologous chromosomes in which this is no longer identical to this, and this is no longer identical to this. And at this point, we call these recombinant chromatids. Why? Well, because none of these are actually identical as in the case of this, where this one was identical to this and this one was identical to this. Now each one of these are genetically unique. So this is basically what happens during ProPhase one of meiosis.
