Snapdragons exhibit incomplete dominance. If two F1 hybrids from the same parental cross both exhibited white flowers, which of the following crosses is most likely to be the parents: (A) pink snapdragon X pink snapdragon; (B) red snapdragon X white snapdragon; OR (C) pink snapdragon X white snapdragon. Explain your answer clearly and be sure to address each of the options separately
I tried using punnet squares but i could not figure it out...please help
Which of the following crosses is most likely to be the parents?
It is c - try using the metric calculus syndrome text by peter marisinel it will explain everything in exact detail - good luck
Reply:C. Pink and white will yield 1 pink: 1white in the offspring. 1/2 of the offspring should be white. That's the highest ratio of white in the problem. (Do RW x WW)
Pink = RW Red = RR White = WW
C. RW x WW
A. Pink and pink will yield 1 red: 2 pink: 1 white. - only 1/4 of the offspring would be white. (Do RW x RW.)
B. Red and white will yield all pink, no white. (Do RR x WW)
