by Sam Lyon

1. Full number in humans of chromosomes in body cells is 46

1.1. Asexual reproduction involves mitosis

2. daughters split 2nd time into Haploid gametes

3. Made up of DNA

3.1. DNA contains 4 bases, shortened to A, T, C and G

4. Stem cells have all their genes switched on at all times

5. Mitosis

5.1. makes genetically identical cells (Clones) for reproduction/growth

5.2. cells dividing

6. Meiosis

6.1. chromosome copied

6.1.1. cells split into 2 daughter cells

6.2. makes egg cells in the ovaries

7. Inheritance & genetics
