Standards:
SC.912.L.16.16 Describe the process of meiosis, including independent assortment and crossing over. Explain how reduction division results in the formation of haploid gametes or spores.
SC.912.L.16.17 Compare and contrast mitosis and meiosis and relate them to the processes of sexual and asexual reproduction and their consequences for genetic variation.
SC.912.L.15.15 Describe how mutation and genetic recombination increase genetic variation.
Objectives:
1. Student knows the effect of meiosis on genetic variation, the process of meiosis (including independent assortment and crossing over), and the advantages and disadvantages of sexual reproduction
2. Student can model meiosis to show the number of chromosomes in the resulting cells.
3. Student can compare and contrast mitosis and meiosis in terms of the number of chromosomes in the resulting cells and their effect on genetic variation.
Daily Essential Questions:
What are the advantages of sexual reproduction over asexual reproduction?
