1) The observed numbers for dominant and recessive types in an F2 generation are 154 and 46. You would assume the expected numbers to be in a ---------- to 1 ratio. would the answer for question 1 be a 3 to 1 ratio i'm really confused. 2) Looking at the observed numbers in question 1 what would your expected number of dominant types be? I don't know please help. 3) Using the same observed numbers in question 1 what would...
