Consider the two cells going through meiosis II during gametogenesis. In one of these two cells, if all of the chomosomes experience non-disjunction, what will be the result at the completion of meiosis? Remember, n represents a copy of the genome.

Two normal cells, n and n; One cell lacks chromosomes : n-nOne cell contain extra set of chromosomes: n+n=2n

Explanation:

If all of the chromosomes experience non-dis-junction in meiosis II, means that sister chromatids failed to separate during meiosis II then

a. half the cells are normal containing n number of chromosomes (n).

b. One cell lacks whole set of chromosomes

c. and one cell with two copies of the chromosomes (n+n).
