Now we replicated and so we produce the cystochromatid that is identical to this chromatid and we produce this second cystochromatid that is identical to this one. And so we have the pair of cystochromatids as shown in the following diagram. So this is after interface takes place. So now let's fast forward to metaphase one of meiosis. This is what we're going to basically see. We're going to have the tetromers align along the equatorial plate.
