Question

which is a correct statement about this illustration? meiosis ii has begun. a diploid cell has become haploid. chromatids have switched. genetic variation within chromosomes has increased.

Explanation:

The image shows crossing - over during meiosis, where chromatids exchange genetic material. This process leads to increased genetic variation within chromosomes. Meiosis II has not begun at this stage, and the cell is still diploid at this point of meiosis I. The key event depicted is the switching of chromatids.

Answer:

Chromatids have switched.
