Outcomes:

• Determine which mutations are favored by the selection agents of predators and food variety and which mutations are neutral.
• Describe which traits change the survivability of an organism in different environments.
• Experiment with environments which produce a stable population of bunnies, a population that dies out, and a population that takes over the world.
• Track genes through multiple generations.
• Compare how dominant and recessive genes get passed onto offspring.

Overview of animal and plant cells. Topics include cell walls, vacuoles, chloroplasts, peroxisomes, lysosomes, mitochondria, etc.

Meiosis is a process that creates sex cells (gametes) with half the number of chromosomes of the parent cell. Meiosis has two stages: meiosis I and meiosis II. In meiosis I, homologous chromosomes pair up and exchange genetic material (crossing over). In meiosis II, sister chromatids separate, creating four haploid cells.

How homologous chromosomes separate into two sets. Prophase I, metaphase I, anaphase I, and telophase I.
