Assume that in watermelon plants the genes for flower color (Y = yellow; y = orange flowers) and fruit shape (R = round; r = oval) are on the same chromosome. You cross two true-breeding plants, one with yellow flowers and round fruit and the other with orange flowers and oval fruit. You take one of the F1 individuals and cross it with a plant that is homozygous recessive for both traits. You get the following in the F2: 300 yellow flowers, round fruit; 300 orange flowers, oval fruit; 100 yellow flowers, oval fruit, 100 orange flowers, round fruit. What is the map distance between the genes for flower color and fruit shape?
