All living creatures are classified into systems and sub-systems based on their similar characteristics. They are divided from bigger groups into smaller groups based on the detail of their similarities i.e. how they look, move, reproduce and how they relate to each other. A practical way of understanding the classification of living organisms is that organisms are linked to other similar organisms via family trees. The classification of all living creatures includes at least four levels: order, families, genus and species.

Answer and Explanation: Nondisjunction occurs when sister chromatids are not pulled apart at anaphase II. This will cause both sister chromatids/ homologous chromosomes to be pulled to just one pole of the cell.
Since the anaphase I stage in Meiosis I occurred without errors, this would result in four haploid gametes being produced.
However, two of these gametes will be normal, will have the normal number of chromosomes. The other two gametes would have an abnormal number of chromosomes and be aneuploid. One would have n+1 number of chromosomes, and the other would be n-1.
