A lot of students approached me about question 2.27 from the Sanders and Bowman textbook. I can't use their question directly, but I came up with a similar one. I like this question because it can be used to practice how branch diagrams are used, and for both phenotype and genotype.
Try this out on your own. I have two videos for the answers. One is for a-c which are phenotype-related and were easier for most students. The second video is for d&e which involve genotypes. Note that you can solve these without using branch diagrams! The student Study Guide and Solutions Manual shows other ways to correctly determine the answers.
