Suppose that height in tomato plant is due to gene R, with the R allele bing dominant to the r allele. You mate a true-breeding tall tomato plant (RR) to a true-breeding short tomato plant. What is the probability that the F1 are tall?

Solution

Tall plant with allele RR is crossed with short plant having alleles rr progeny will have Rr genotype they are all tall phenotypically. Probability is that they will be tall
