A cell at the 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 plates and thus the cell contains more number of chromosomes as compared to other dividing cells. This would result in
Polyploidy
Somaclonal variation
Polyteny
Aneuploidy
Polyploid cells have a chromosome number that is more than double the haploid number, e.g. Triticum aestivum (wheat) is a hexaploid (6n). Hence, the correct answer is option 1.
