What major event occurs during interphase? What is the ploidy of the DNA at the end of meiosis I? What about at the end of meiosis II? How are meiosis I and meiosis II different? Why do you use non-sister chromatids to demonstrate crossing over? What combinations of alleles could result from a crossover between BD and bd chromosomes?

How many chromosomes were present when meiosis I started? How many nuclei are present at the end of meiosis II? How many chromosomes are in each? Identify two ways that meiosis contributes to genetic recombination.

Why is it necessary to reduce the number of chromosomes in gametes, but not in other cells? Blue whales have 44 chromosomes in every cell. Determine how many chromosomes you would expect to find in the following: Daughter Cell from Mitosis: Daughter Cell from Meiosis II: Research and find a disease that is caused by chromosomal mutations.

When does the mutation occur? What chromosomes are affected? What are the consequences? Diagram what would happen if sexual reproduction took place for four generations using diploid 2n cells. Record your hypothesis from Step 1 in the Procedure section here. What do your results indicate about cell cycle control?


Be specific when you explain why or why not. Why do cells which lack cell cycle control exhibit karyotypes which look physically different than cells with normal cell cycle.Jan 14,  · Introduction and Objective In Mr.
