(1) Chromosomes will not condense

(2) Chromosomes will be fragmented

(3) Chomosomes will not segregate

(4) Recombinantion of chromosome arms will occur

Which of the following options gives the correct sequences of events during mitosis?

(1) Condensation → nuclear membrane disassembly → crossing over → Segregation → telophase

(2) Condensation → nuclear membrane disassembly → arrangement at equator → centromere division → Segregation → telophase

(3) Condensation → crossing over → nuclear membrane disassembly → Segregation → telophase

(4) Condensation → arrangement at equator → centromere division → Segregation → telophase

A cell at telophase stage is observed by a student in a plant brought from the field. He tells his teacher that his 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) polyploidy

(2) somaclonal variation

(3) polyteny

(4) aneuploidy
