A cell at telophase stage is observed by a student in a plant brought from the field. He tells his teacher that this cell is not like other cells at telophase stage. There is no formation of cell plate and thus the cell is containing more number of chromosomes as compared to other dividing cells. This would result in

1. Aneuploidy
2. Polyploidy
3. Somaclonal variation
4. Polyteny

Correct answer: Polyploidy

Solution

Without cell plate formation, the cell may not complete cytokinesis, so the chromosome sets remain in one cell. This produces a cell with extra complete sets of chromosomes, which is polyploidy.
