Lesson
Framing Question • What are the mechanisms by which an organism’s genome is passed on to the next generation?
Learning Objectives • Describe, using diagrams, the sequence of events involving DNA in meiosis from chromosome
duplication through chromosome segregation. Explain how meiosis is different from mitosis.• Given an offspring’s genotype, predict the stage(s) of meiosis that could have been abnormal• Propose a testable hypotheses to explain observations
Active Learning Strategies• Interactive lecture, Think-pair-share, Story telling, Small and larger group discussion, Optional
drawing/labeling
Assessment Strategies• Interpretation of diagrams of meiosis, drawing chromosomes at different stages of meiosis, clicker-type
questions
Inclusive Teaching Strategies• Potential to engage many individuals since questions about reproduction are typically very interesting
to many people, story can relate to some religious perspectives

Introduction
When I was a graduate student, one of the staff in our department at Carnegie-Mellon University told me about her involvement in a women’s group that met annually in the woodlands of Pennsylvania to “frolic in nature.” My recollection of her description of this group suggested that an important topic of their conversation was how to eliminate the need for men in human society. I learned from her that a variety of vertebrates could produce babies without any involvement of sperm and, therefore, of males. She introduced me to the Beltsville White turkey breed, which produces unfertilized eggs that can hatch into little male turkeys that can go on to mate and produce viable offspring. I was fascinated with both the idea that an unfertilized egg could actually hatch to produce a viable baby bird (!) and that the baby bird would be male.
Fast forward about 10 years. I was teaching non-majors’ biology at the University of Washington and trying to interest my students in the stages of mitosis. After several abortive attempts spanning several years, I boiled it down to just metaphase and the products – if they could just line the chromosomes up at metaphase and identify the products of cell division, we’d call it a day.
