#SCPH01 Biochemistry

In watermelons, bitter fruit (B) is dominant over sweet fruit (b), and yellow spots (S) are dominant over no spots (s). The genes for these two characteristics assort independently. A homozygous plant that has bitter fruit and yellow spots is crossed with a homozygous plant that has sweet fruit and no spots. If an F1 plant is cross with the heterozygous for bitter and no spots, what phenotypes ratio are expected in the offspring?
