Question

many single - celled eukaryotic organisms have evolved complex life cycles that include sexual reproduction. this means that: genetic material from two haploid cells is combined. diploid cells must undergo mitotic cell division in order to reproduce. haploid cells must undergo meiotic divisions to form gametes.

Explanation:

Sexual reproduction in single - celled eukaryotes involves combining genetic material from two haploid cells. Haploid cells are involved in meiosis to form gametes, and diploid cells divide mitotically for growth and asexual reproduction. The key here is the combination of genetic material from two haploid cells in sexual reproduction.

Answer:

genetic material from two haploid cells is combined.
