By what mode of cell division would you expect sperm cells to be formed in the haploid male bee? Explain the possible mechanism. What would happen during anaphase and anaphase 1 in individual posing an odd number of chromosomes? Supposed mitotic and meiotic had never evolve. What do you think would have been the consequences?

The function of Paclitaxel was described in the simulation as preventing the microtubules from forming properly during anaphase. How would this effect cells that are in the G2 phase of the cell cycle? Could Paclitaxel have an effect on the formation of gametes? Explain your answer.
At what stage of mitosis can the kind and number of chromosomes be easily detected and determined? How does non disjunction in meiosis lead to numerical chromosomal aberration? If cell division during gametogenesis is non meoitic, what is its consequence to the future generations of diploid organisms? What is the relationship between meiosis and fertilization?
A sperm cell from the fruit fly Drosophila melanogaster contains four chromosomes. How many chromosomes would be present in a spermatogonial cell about to enter meiosis? How many chromatids would be present in a spermatogo- nial cell at metaphase I of meiosis? How many would be present at metaphase II?
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?
