7. I can describe and explain the process of meiosis and how it results in greater variation than asexual reproduction.
8. I can explain how independent assortment, crossing over, and random fertilization causes the increase variation in sexual reproduction.
9. I can explain how crossing over results in the recombination of chromosomes in the gametes.
