Marshmallow Babies
Eighth graders interpret the genotypes and phenotypes, then pair up chromosomes.
Beyond Benign
Punnett Square Possibilities
Discover possible genetic outcomes through Punnett Squares. Learners continue studying genetic traits in the 10th lesson in the 17-part series. After determining the father of Sparky's kittens, scholars now attempt to predict the traits...
