An organism is described as 2n = 20. How many chromosomes are present in a meiotic metaphase II cell from this organism?

Could you please explain this to me? I am in a entry level genetics course. Please speak in easy to understand terms. Thank you so very much.

#10# chromosomes

Explanation:

When a diploid (2n) cell undergo meiosis it remains diploid till Telophase-I. After Telophase-I cells formed are haploid (n).

From Prophase-II to Telophase-II cells are in haploid (n) state.

Cells in metaphase-II phase is haploid (n). So, the number of chromosomes in the cell at this phase is #10#.
