Explanation:

The cell, according to the karyotype, has two (2) X chromosomes and a Y chromosome.  A  cell should have either XX or XY sex chromosome pair.

This disorder can be defined as Klinefelters syndrome in humans with XXY sex chromosomes. This anomaly is caused by the non-dosjuntion of homologous chromosomes during  meiosis I metaphase.  

Homologous chromosomes usually line up the metaphase plate of the parent cell before spindle fibers from either pole of the cell attach to the kinetochore (at the centromere) of either chromosome, of a homologous pair, and then separates them during anaphase I. If there is an issue at this stage such as with the spindle fibers, non-disjunction can occur resulting in this disorder (aneuploidy).

One daughter cell will have two homologous chromosomes of a pair while the other with have none of that pair.
