Question

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

Explanation:

The illustration shows crossing - over (chromatid exchange) between homologous chromosomes, which occurs during meiosis I. This process increases genetic variation within chromosomes. A diploid cell doesn't become haploid here (haploidization is after meiosis I and II), meiosis II hasn't begun (this is meiosis I - related), and chromatids switching is crossing - over which leads to increased genetic variation.

Answer:

Genetic variation within chromosomes has increased
