  2. What is the process called that produces gametes?

  3. Where in the body are germ cells found?

  4. What word describes two chromosomes that always exist as a homologous pair in a cell?

  5. A cell that is diploid and created by mitosis is what type of cell?

  6. How many nuclear divisions take place during meiosis?

  7. How many nuclear divisions take place during mitosis?

  8. Name at least two ways that meiosis is different from mitosis?

  9. In what phase of meiosis do homologous chromosomes line up at random down the equator of the cell?

  10. In what phase of meiosis do sister chromatids separate?

  11. In what phase of meiosis does crossing over take place?

  12. What is the major difference between interphase 1 (the interphase that takes place before meiosis 1) and interphase 2 (the interphase that takes place between meiosis 1 and meiosis 2?

  13. What are at least two differences between a gamete and a somatic cell?

  14. In which part of meiosis does the reduction in the number of chromosomes, from diploid to haploid, take place?
