As with the rest of my curriculum, I’ve gone through the College Board’s Course and Exam Description for AP Biology and extracted the following Learning Objectives, Enduring Understandings, and pieces of essential knowledge. This is what I’m using to inform the development of my on-line tutorials about meiosis, and the instruction I’m delivering to my own students at BHS. I’d love to know what you think.

Learning Objectives (two of these can also go to mitosis)

  1. LO 3.28:The student is able to construct an explanation of the multiple processes that increase variation within a population.  (EK: 3C2)
  2. LO 3.9:The student is able to construct an explanation, using visual representations or narratives, as to how DNA in chromosomes is transmitted to the next generation via mitosis, or meiosis followed by fertilization  (EK: 3A2)
  3. LO 3.1:The student is able to represent the connection between meiosis and increased genetic diversity necessary for evolution  (EK: 3A2)
  4. LO 3.11:The student is able to evaluate evidence provided by data sets to support the claim that heritable information is passed from one generation to another generation through mitosis, or meiosis followed by fertilization.  (EK: 3A2)
  5. LO 3.12:The student is able to construct a representation that connects the process of meiosis to the passage of traits from parent to offspring.  (EK: 3A3)
  6. LO 3.27:The student is able to compare and contrast processes by which genetic variation is produced and maintained in organisms from multiple domains(EK: 3C2)

Enduring Understandings and Essential Knowledge

  1. Meiosis creates haploid gametes (3.A.2.c)
  2. Pairing of homologues
  3. Crossing over between homologues
  4. Random orientation before separation
  5. Independent assortment resulting from anaphase 1
  6. Fertilization restores diploid condition, increases genetic variation in population
