1. The problem statement, all variables and given/known data First question of this particular page http://www.hourlybook.com/ncert-questions-pmts-cell-cycle-cell-division/ 2. Relevant equations the answer is given as C. 3. The attempt at a solution But i didn't understand because in last phase i.e D dna content is again reduced to 2c.But in mitosis I have studied that it is equational division so each daughter cell after mitosis should have 4C DNA content not 2C. I think it is called equational division just because (1)number of chromosome remains same but DNA content is halved after mitosis. (2)Each daughter cell has same number of chromosome as mother cell but half amount of DNA as compared to mother cell. (3)Ploidy is related to number of chromosome not with DNA content am I right?
