Why Lesson Planet?
Using plastic Easter eggs to represent parent phenotypes, genetics enthusiasts simulate the passing of alleles. They record the phenotype of each half of the egg, one representing the mother's and one representing the father's. They determine the genotypes and then solve a Punnett square for their cross. Once they predict the genotype and phenotype of the offspring, they open the egg. You will have pre-planted colored candies within the eggs according to a corresponding phenotype. This is a clever lesson for making the passing of alleles more visual.
