How do the chromosomes in most cells of an organism, such as the leaf cells of a plant, compare to the chromosomes in its reprod
Lunna [17]

Answer:

Reproductive cells have half the amount of chromosomes than body cells

Explanation:

I think that you are talking about body cells when you say "most cells in an organism." If that is the case, then the reproductive cells, sperm and egg cells, have half the amount of chromosome than body cells.

For example: Human body cells have 46 chromosomes. Human reproductive cells has 23 chromosomes.

In sexual reproduction, each parent gives 1/2 of a full set of chromosomes to create the full set needed for an organism.
