This is a handy lesson on genotype and phenotype. It is the second in a series on middle school genetics (see Genetics - Punnett Squares). It includes a foldable for the notebook, a homework (or in-class) assignment, and some accommodations and modifications for kids with special needs. I have used this lesson for the last few years and have been pleased with the results. For the entire week's unit, see my Genetics Week 1.
