Which of the following best describes how the process of crossing over during meiosis leads to an increase in genetic diversity?

Eukaryotes have membrane-‐bound organelles, while prokaryotes have few specialized structures. During prophase I, DNA segments are exchanged between homologous chromosomes, resulting in different combinations of alleles. Mitosis involves one division cycle and results in diploid daughter cells, while meiosis consists of two division cycles and results in haploid gametes.
