Problem:
Analyzing Gene question
Question 1: How can you tell if a trait is determined by more than one gene?
Question 2: What ratios of phenotypes in the F2 generation would you expect if a trait is determined by a single gene?
Question 3: If you get 9:3:3:1 phenotypic ratios in the F2, and you observe phenotypes that are different from those of either parent, how many genes would you say are involved in the inheritance of that trait?
Please explain your answer and be as specific as possible.
