Now, we have nondisjunction take. Place in both of these cells. Now, of course, we can have nondisjunction taking place in one of these two cells, but let's assume that nondisjunction takes place in both of these cells. What will happen is so we have one fiber forms a connection, the other one doesn't. One fiber forms a connection, the other one doesn't. And so when we have the segregation process take place, this entire pair of cystochromatids moves to one cell.
