The correct answer is this one: "C) Nnew = Nold + 2." A student is studying a process in which a diploid cell becomes haploid. The CORRECT mathematical model for the process if Nnew is the number of chromosomes in the haploid cell and Nold is the number of chromosomes in the diploid cell is this: new = Nold + 2
Here are the choices.
A) Nnew = 2·Nold
B) Nnew = Nold 2
C) Nnew = Nold + 2
D) Nnew = Nold × 2
