1. Compare and contrast mitosis and meiosis.
2. What major event occurs during interphase
Trial 1 - Meiotic Beads Diagram:
Trial 2 - Meiotic Division Beads Diagram:
- In this experiment, how many chromosomes were present when meiosis I started?
- In this experiment, how many nuclei are present at the end of meiosis II? How many chromosomes are in each?
- 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? List two reasons.
- 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?
- 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.
