13. In another species of berry, Rass berrylis, the allele for yellow fruit (F) is dominant to the allele for red fruit (f), and the allele for thorny stems (T) is dominant to the allele for thornless stems (t). The gene for fruit colour is 17.4 map units from the gene for stem thorniness. Draw a Punnett square to illustrate the cross between a Rass b. with red berries and thornless stems and a plant that was heterozygous for both characteristics. (The parents of the heterozygous plant were yellow-fruiting and thorny, and red- fruiting and thornless, and were homozygous for both traits.)
