Which of the following is the best explanation for why the chromosome numbers above are all even?
Diploid Chromosome Number
Fruit Fly 8
Human 46
Goldfish 94
1)
The diploid chromosome number represents two sets of chromosomes, one from each parent, so it is always an even number.
2)
Animal cells always have an even number of chromosomes, and plant cells always have an odd number of chromosomes.
3)
The number of chromosomes present in a diploid cell doubles for each generation because there are two parents.
