Solution
The correct option is B Polyploidy
- Polyploidy is the state of a cell or organism having more than two paired sets of chromosomes.
- Aneuploidy is the presence of an abnormal number of chromosomes in a cell, for example a human cell having 45 or 47 chromosomes instead of the usual 46. It does not include a difference of one or more complete sets of chromosomes.
- In genetics, a deletion) is a mutation (a genetic aberration) in which a part of a chromosome or a sequence of DNA is lost during DNA replication.
- Gene duplication is a major mechanism through which new genetic material is generated during molecular evolution. It can be defined as any duplication of a region of DNA that contains a gene.
So, the correct answer is 'Polyploidy'.
