  • Q20
    Why do sexually reproducing organisms most likely create offspring with more genetic variation than asexually reproducing organisms?
    Cells produced by sexual reproduction have more DNA than cells produced by asexual reproduction.
    Sexual reproduction is caused by the union of cells from two different organisms, while asexual reproduction is caused by one duplicating cell.
    During sexual reproduction cells go through mitosis to increase diversity, while in asexual reproduction meiosis occurs to keep things unchanged.
    Sexual reproduction creates four new cells, while asexual reproduction creates only two new cells.
