And notice that each one of the chromatids on the chromosomes are genetically different from one another. So this chromos or this chromatid is different than this chromatid, and this chromatid is different than this one, and it's different than this one. So each one of these chromatids have their own unique genetic information, and that's exactly what our recombinant genetic recombination actually does. So this is the major process that takes place in ProPhase one that differentiates ProPhase one from ProPhase of mitosis. Now let's move on to metaphase one of meiosis. So during metaphase one, the spindle fibers actually attach themselves to the kinetic or region of each one of these tetrids.
