We have 2 types of cells in our body: somatic (body cells) and gametes (sperm and egg).
Somatic cells are called diploid (or 46 chromosomes) whereas gametes are haploid (23
chromosomes). The production of each is similar but with some big differences.
Mitosis is asexual and one cell creates 2 identical copies of itself. Mitosis is sexual and
creates 4 copies of itself that are nonidentical.
In this class today we will:
1. Review and practice Punnett squares and how inheritance works
2. You will model mitosis and meiosis using this as a guide:
3. Some terms we will define first are
a. Sister chromatids
b. Homologous pairs
c. Cell equator
d. Spindle fibers
e. Chromatin
f. Chromosomes
g. Centromere
4. Using the link in number 2, you will make a playdough model of both mitosis and
meiosis
5. When you are done”
Mitosis
Divisions (how many)
Outcome (number of cells
created)
Ploidy (haploid or diploid)
Use (body or gametes)
Genetics (identical or
variation)
Meiosis
