In anaphase, we have the process of disjunction. And disjunction basically means our spindle fibers begin to pull on our chromosomes and we separate our chromosomes. So these three chromosomes begin to go onto the left side and these other three begin to move to the right side. So we separate our tetras. So during anaphase one, this junction occurs, that is, the chromosome pair in the tetra are separated two opposite poles. Now, notice one important point.
