Which of the following best explains why the chromosome number is an even number in organisms?

• It is only by coincidence, many organisms have an odd number
• The diploid number is always even so that when mitosis occurs each cell gets the same number of chromosmes
• The diploid chromosome number represents pairs of chromosomes, one from ech parent, so that it is always an even number
• Chromosomes double very time the cell divides, so after the first division, the number is always even
