Which of the following is the best explanation for why the chromosome number is an even number in each of these organisms?
a. It is only a coincidence; many other organisms have an odd number of
chromosomes.
b. The chromosome number is always even so that when mitosis occurs
each new cell gets the same number of chromosomes.
C. The chromosome number represents pairs of chromosomes, one from
each parent, so it is always an even number.
d. Chromosomes double every time the cell divides, so after the first
division, the number is always even.
