Problem

You have isolated a single cell from a diploid organism. Which of the following would indicate that the cell was at metaphase of meiosis I and NOT metaphase of meiosis II?

A. All the chromosomes were composed of one chromatid.

B. It has a metaphase plate.

C. Homologous chromosomes were present.

D. All the chromosomes were composed of two chromatids.

E. There was only one copy of ech type of chromosome.

Solution

In general, meiosis is the cell division mechanism of sexually reproducing diploids to produce gametes. The aim of meiosis is to produce haploid gametes from diploid cells. This general process, however, is actually composed of two consecutive cell divisions: meiosis I and meiosis II. This results in 4 haploid daughter cells.
