A diploid species has four chromosomes per set for a total of eightchromosomes in its somatic cells. Draw such a cell as it wouldlook in late prophase of meiosis II and prophase of mitosis. Discuss how prophase of meiosis II and prophase of mitosis differfrom each other, and explain how the difference originates.
A cell containing 40 chromatids at the beginning of meiosis would at its completion produce cells containing how many chromosomes?
After anaphase and telophase, mitosis is complete, but meiosis is not. What are the differences between the daughter cells of mitosis and meiosis I at this point?
