Problem:
Question 1: Why do both the RR and Rr genotype produce round peas? Explain.
Question 2: We call some traits dominant and others recessive and in class we related this to their respective alleles. Explain, in terms of protein function, why some traits are expressed when alleles are heterozygous.
Question 3: Does the rr genotype result in a gain or loss of function? How could either a loss or gain of function be evolutionarily important?
Please read all the questions carefully and answer them.
