1. Why must DNA replicate before cells divide? You may wish to diagram the
processes without DNA replication to help you answer this question.
2. Gametes (sex cells) only have half the genetic information as other body cells.
How many chromosomes do human gametes have? _______
2a. What are the female gametes called? _____________ male? _________
3. Which process produces gametes, mitosis or meiosis? ________________
4. Could mitosis produce gametes? Why or why not?
5. Look at the diagram of meiosis on page 1. Where do you seeing crossing-over
of chromosomes (pieces of a chromosomes breaking off and going to another)?
6. Genetic information is combined when crossing-over occurs. How will this
effect the genotype of the offspring?
7. Name two similarities and two differences between mitosis and meiosis.
