Astudent is studying mitosis, in which a cell divides to form two cells. which of these shows the correct mathematical model for the process if nold shows the number of chromosomes in the parent cell and nnew shows the number of chromosomes the individual daughter cells? a) nnew = nold b) nnew = nold/2 c) nnew = 2 × nold d) nnew = 4 × nold

The right answer is A)Nnew = Nold  

Mitosis is a process of cell division that makes it possible to obtain from a mother cell two identical daughter cells to each other (and at the same time to the mother cell). So their chromosome number of the daughter cells is identical to those of the mother cell.
