Explanation:
Chromosomal abnormalities are caused when the chromosome pair fails to disintegrate through a process called non-disjunction. The non-disjunction of chromosomes usually takes place at the anaphase I or II of meiosis I which involves the X and Y chromosomes.
The abnormality observed with 45 chromosomes or reduction in one sex chromosome or 45, XO is caused when one X copy of a chromosome is completely absent in the cell.
