The next three questions are all related: You are testing the null hypothesis that the outcome of a dihybrid cross conforms to a 1:1:1:1 ratio resulting from a cross between a heterozygous individual (AaBb) and a homozygous recessive individual (aabb), and that any differences are due to chance. Part I: How many degrees of freedom are there? Question 2 Part II: Assuming ap-value cut-off of 0.05, what is the critical value for this test? Enter your answer to three decimal places (e.g., 8.888).
