In a dihybrid cross between RrTt and RRtt, what are the genotype and phenotype ratios of the offspring, assuming R and T are dominant? R codes for round seed, while r codes for wrinkled seed. T codes for tall height, while t codes for short height. (Show your Punnett Square). Hint: Do the Punnett Square for each trait separately and then combine them using the branch diagram

Since R is dominant over r and T is dominant over t to get round seed and short ones the genotype of the progeny should have rr and tt. To get that kind of progeny one r should be from one parent the other r should be from the other parent. So as we can see only one parent has r SO we can come to the conclusion that no wrinkled shaped seed would be produced. I hope u get what I am saying !
