Aneuploidy:

Aneuploidy is a form of chromosomal abnormality in which one chromosome is extra or one chromosome is absent.

Polyploidy:

Polyploidy is the process of doubling the genome that results in creatures having several sets of chromosomes.

Difference between polyploidy and aneuploidy

Aneuploidy

Polyploidy

1. Aneuploidy is commonly described as the situation of having an abnormal number of chromosomes in a haploid pair.1. Polyploidy occurs when a completely new pair of chromosomes is added.
2. It is widespread among people.2. It is quite unusual in humans.
3. They result in deadly chromosomal abnormalities.3. They create deadly triploid and tetraploid conditions.
4. Aneuploidy causes nullisomy.4. Polyploidy results in triploidy.
5. It is classified into two types: hyperploidy and hypoploidy.5. It is classified into two types: autopolyploidy and allopolyploidy.
6. It is caused by the non-disjunction of two homologous chromosomes.6. It develops as a result of cytokinesis failure following the telophase stage.
7. In the case of animals, aneuploidy does not necessarily end in sterility.7. Polyploidy in animals invariably leads to sterility.
8. Down's syndrome, Edward's syndrome, and Turner's syndrome are examples of aneuploidy8. Triploidy, with 69 chromosomes (sometimes called 69, XXX), and tetraploidy with 92 chromosomes (sometimes called 92, XXXX) are the examples of polyploidy
