Question

PLEASE PLEASE HELP
The table below provides the number of chromosomes found in the body cells of various types of organisms.


Diploid Chromosome Number
Fruit Fly
8
Human
46
Goldfish
94

Which of the following is the best explanation for why the chromosome numbers above are all even?
The diploid chromosome number represents two sets of chromosomes, one from each parent, so it is always an even number.
Animal cells always have an even number of chromosomes, and plant cells always have an odd number of chromosomes.
The diploid chromosome number is always even to ensure that equal numbers of chromosomes end up in each daughter cell during meiosis.
The number of chromosomes present in a diploid cell doubles for each generation because there are two parents.

Answer 1

"The number of chromosomes present in a diploid cell doubles for each generation because there are two parent" is the one among the two statements that is the best explanation for why the chromosome numbers above are all even. The correct option among the two options that are given in the question is the second option. 

Answer 2

Answer:

The diploid chromosome number represents two sets of chromosomes, one from each parent, so it is always an even number.

Explanation:

A diploid cell or organism has half its chromosomes from one parent, and the other half from the other parent.

"Two sets of chromosomes" means that every cell will have two chromosomes 1, two chromosomes 2, two chromosomes 3, etc. One comes from the mother and the other comes from the father.

The answer "The number of chromosomes present in a diploid cell doubles for each generation because there are two parents." is incorrect because a diploid cell doesn't normally double its chromosome number in a permanent way.

A special type of cells called germ cells can reduce their chromosome number by half in order to produce haploid gametes with an uneven number of chromosomes. Once two gametes from each parent unite, a zygote is formed with the restored diploid and even chromosome number.
