So once again, let's assume that nondisjunction takes place in anaphase two and not anaphase one. And so what that means is these mitotic spindle apparatuses or the spindle apparatus basically forms correctly and these fibers extend into onto these cystochromatid pairs and now segregation takes place and we form these two cells as shown. So these two haploid male cells and now once again, let's assume that nondisjunction took place during the second phase of meiosis. So we have metaphase two. Now, this cell basically divides normally and so these fibers are able to attach to each one of these cystochromatids. So this one and this one.
