Genetics Practice: Beyond the Basics

For Students 9th - 12th
What do you get when you cross a purple with a white? Genetics geniuses figure it out with a Punnett square. On this assignment, they must solve crosses for incomplete dominance, codominance, lethal dominance, and sex-linked genes. It is...
