Suppose that for an organism, 2n=8. How many chromosomes do the organism's gametes contain?

If 2n stands for the diploid number (the number of chromosomes in all the body cells), then the gametes will contain a haploid number (half of the diploid number).

This is so, when sperm and egg (gametes) unite, the haploid number will be restored.

I hope this helps. Thanks for asking.

To determine how many chromosomes the organism's gametes contain, we need to understand the concept of haploid and diploid cells.

In a diploid organism, the number of chromosomes is represented by 2n, where n is the number of unique chromosomes. The diploid cells, also known as somatic cells, contain two sets of chromosomes, one inherited from each parent.

On the other hand, haploid cells, such as gametes, have half the number of chromosomes, represented by n. Gametes are specialized cells involved in sexual reproduction, which, upon fertilization, combine to form a new diploid organism.

So, in this case, we are given that 2n = 8. To find the number of chromosomes in the organism's gametes (n), we can rearrange the equation:

2n = 8
Divide both sides by 2:
n = 4

Therefore, the organism's gametes contain 4 chromosomes.
