Summary Introduction
To explain:
The relationship between aneuploidy and nondisjunction.
Concept introduction:
The chromosomes are formed by the packing of DNA (deoxyribonucleic acid) onto the protein molecules. The number and the structure of the chromosomes are maintained as such during the meiosis, however, due to some error, the number or the structure might change.
