Description
Today we did a quick lesson on Punnett Squares. I don’t like to make this a major topic; in my opinion, Punnett Squares tend to promote an overly simplistic view of genetics. So I like to teach them for what they are: a quick way to make simple genetic predictions.
I started off by telling the story of how Gregor Mendel discovered dominant and recessive genes through his experimentation with pea plants. Then we completed a packet that included other genetics examples, like attached/unattached earlobes, the dwarfism gene, and cystic fibrosis. Students had to figure out which gene was dominant, fill out a Punnett Square, and then make predictions about the offspring.

NGSSMS-LS3-1
Develop and use a model to describe why structural changes to genes (mutations) located on chromosomes may affect proteins and may result in harmful, beneficial, or neutral effects to the structure and function of the organism. Emphasis is on conceptual understanding that changes in genetic material may result in making different proteins. Assessment does not include specific changes at the molecular level, mechanisms for protein synthesis, or specific types of mutations.
NGSSMS-LS3-2
Develop and use a model to describe why asexual reproduction results in offspring with identical genetic information and sexual reproduction results in offspring with genetic variation. Emphasis is on using models such as Punnett squares, diagrams, and simulations to describe the cause and effect relationship of gene transmission from parent(s) to offspring and resulting genetic variation.
