Answer:
Two normal haploid daughter cells (n), one daughter cell with one extra chromosome (n+1) and one daughter cell with one less chromosome from the haploid set (n-1).
Explanation:
Failure of sister chromosomes to separate from each other at the end of metaphase II is called as nondisjunction at meiosis II. It leads to formation of four daughter cells with different number of chromosomes. Out of total four cells, two daughter cells have a complete haploid set of chromosomes and are normal. The third daughter cell has one extra chromosome and is denoted as "n+1". On the other hand, the fourth daughter cell lacks one chromosome from the haploid set and is denoted as "n-1".
