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

1 answer

Best answer

Answer: 2. Polyploidy

Failure of cell plate formation in telophase (cytokinesis fails) leaves a cell with a doubled chromosome number. Cells with whole extra sets of chromosomes are polyploid. Aneuploidy is gain or loss of one or a few chromosomes, and polyteny refers to many chromatids in giant chromosomes.
