- Now that you've learned about mitotic and meiotic cell division, you understand that the process of mitosis results in cells that are identical to the parent cell whereas in meiosis, the daughter cells that are produced are genetically different from the parent cell. Meiosis introduces variation into populations of sexually reproducing organisms while mitosis produces cells for growth and cell specialization. In this post you will demonstrate understanding of how meiosis contributes to genetic variability and why this variability is important. How would children look if humans would reproduce through mitosis instead of using meiosis? Would there be any pitfalls in a population of humans if mitosis were the primary method for reproduction? Please remember to add a question to engage your classmates in the discussion.arrow_forwardExplain how to arrive at the estimate that one human couple can produce over 70 trillion unique offspring.arrow_forwardWhat are the four biological events associated with sexual reproduction that contribute to the diversity of a gene pool?arrow_forward
