meiosis in a cell with three pairs of homologous chromosomes produces eight unique gametes (crossovers aside). Use the same technique to determine how many unique gametes can be produced by a cell that has four pairs of homologous chromosomes. A human female can release about 350 eggs during her reproductive years. What is the chance that she would generate the same gamete twice in her lifetime?

Assume that a meiotic-nondisjunction event causes trisomy 8 in a newborn. If two of the three copies of chromosome 8 are absolutely identical, at what point during meiosis did the nondisjunction event take place?
It is possible that an alternative mechanism for generating germ cells could have evolved. Consider meiosis in a germ cell precursor (a cell that is diploid but will go on to make gametes). If the S phase were skipped, which meiotic division (meiosis I or meiosis II) would no longer be required?
Compare meiotic anaphase I with meiotic anaphase II. Which meiotic anaphase is most similar to the mitotic anaphase?
How would the mutation of a single chromosome in metaphase 1 of meiosis affect the process of meiosis? Use a simple cell with two chromosomes, what is the ratio of gametes with the mutation vs without the mutation?
In human spermatogenesis, mitosis of a stem cell gives rise to one cell that remains a stem cell and one cell that becomes a spermatogonium. (a) Draw four rounds of mitosis for a stem cell, and label the daughter cells. (b) For one spermatogonium, draw the cells it would produce from one round of mitosis followed by meiosis. Label the cells, and label mitosis and meiosis. (c) Explain what would happen if stem cells divided like spermatogonia.
In a comparison of the stages of meiosis to the stages of mitosis, which stages are unique ... to meiosis and which stages have the same events in both meiosis and mitosis?
In human spermatogenesis, mitosis of a stem cell gives rise to one cell that remains a stem cell and one cell that becomes a spermatogonium. Draw four rounds of mitosis for a stem cell and label; the daughter cells. For one spermatogonium, draw the cells it would produce from one round of mitosis followed by meiosis. Label the cells, and label mitosis and meiosis. What would happen if stem cells divided like spermatogonia?
A human cell that has gone through the second division of meiosis will contain how many chromosomes?
Explain why the daughter cells produced by meiosis NEED to be genetically different from each other, whereas the daughter cells produced by mitosis NEED to be identical.
If gametes had the same number of chromosomes as body cells, and an organism had 24 chromosomes in its body cells, how many chromosomes would it have after three generations? How does this illustrate the necessity of meiosis for gamete formation?
imagine a giraffe whose diploid is 30. A)Under what circumstances would the giraffe go through a process of meiosis? . b) what will be the final result of this meiosis for the giraffe (# of cells + # of chromosomes/cells)
