Why Lesson Planet?
Eighth graders take a short quiz on genotypes and phenotypes. As a class, they are introduced to the concept of Punnett Squares and listen to a description of Gregor Mendel's pea experiment. In groups, they complete Punnett Squares to determine the probability of an offspring having certain traits. To end the instructional activity, they complete a problem to determine the correct combination of genes related to hairless dogs.
