2. Mitosis
Makes body cells
2 with same chromosomes. 12 12 12

3. Mitosis A cat has 22 chromosomes in a body cell:
One cell goes under mitosis. What will you have after mitosis? (# of cells) (#of chromosomes)

4. Meiosis Making sex cells Sex cells have half the normal chromosomes
Sperm in males
Eggs in females
Sex cells have half the normal chromosomes
Fertilization
When sperm and egg combine dna.
Need half # so combination is total
