Question

which of the following shows metaphase 1 in meiosis (centrosomes are at the left and right poles of each cell)?

Explanation:

In Metaphase I of meiosis, homologous chromosomes pair up and align at the equatorial plate of the cell. In Cell 1, we can observe two pairs of homologous chromosomes (one blue and one red) lined up side - by - side, which is characteristic of Metaphase I. In Cell 2, the chromosomes are lined up in a single file, which is more characteristic of Metaphase II (where sister chromatids align, not homologous chromosomes).

Answer:

Cell 1.
