20.
Which of the following best explains why the chromosome number is an even number in organisms?
a)
It is only by coincidence, many organisms have an odd number
b)
The diploid number is always even so that when mitosis occurs each cell gets the same number of chromosmes
c)
The diploid chromosome number represents pairs of chromosomes, one from ech parent, so that it is always an even number
d)
Chromosomes double very time the cell divides, so after the first division, the number is always even
