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
A
polyploidy.
B
somaclonal variation.
C
polyteny.
D
aneuploidy.
Explanation
Chromosome doubling without cell division gives polyploidy.
Detailed Solution
A cell with more than two genomes is polyploid (autopolyploid or allopolyploid). A cell containing more chromosomes because no cell plate was formed shows polyploidy.
