Description of this paper

What is the state of the DNA at the end of meiosis




Using the space below, and using blue and red markers, draw a diagram of your beads in each stage. Beside your picture, write the number of chromosomes present in each cell.;Meiosis I;Prophase I;Metaphase I;Anaphase I;Telophase I;Meiosis II;Prophase II;Metaphase II;Anaphase II;Telophase II;Questions;1. What is the state of the DNA at the end of meiosis I? What about at the end of meiosis II?;2. Why are chromosomes important?;3. How are Meiosis I and Meiosis II different?;4. Name two ways meiosis contributes to genetic recombination.;5. Why do you use non-sister chromatids to demonstrate crossing over?;6. How many chromosomes were present when meiosis I started?;7. Why is it necessary to reduce the chromosome number of gametes, but not other cells of an organism?;8. If humans have 46 chromosomes in each of their body cells, determine how many chromosomes you would expect to find in the following;a. Sperm;b. Egg;c. Daughter cell from mitosis;d. Daughter cell from Meiosis II;9. Investigate a disease that is caused by chromosomal mutations. When does the mutation occur? What chromosome is affected? What are the consequences?
