Principles of Inheritance and Variation
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)somaclonal variation
- (B)polyploidy
- (C)aneuploidy
- (D)polyploidy
The NCERT line that answers it
Verbatim lineFailure of cytokinesis after telophase stage of cell division results in an increase in a whole set of chromosomes in an organism and, this phenomenon is known as **polyploidy**.

The answer appears as a continuous sentence in NCERT. This is that sentence.
How this line gives the answer
0, emb=1.0, combined=1.0). Verified: high — The span explicitly states that failure of cytokinesis after telophase results in polyploidy, which directly matches the scenario described in the question where no cell plate forms and chromosome number increases.
