Question: 5 2 positions of flowers on the stems of garden...

Question details
5. (2) Positions of flowers on the stems of garden pea are controlled by two alleles of a particular locus. If flowers grow in the axils they carry a dominant (T) allele and if they are terminal they carry two recessive (t) alleles. Instead, coloured flowers are determined by either a dominant (C) allele or are white and determined by a recessive (c) allele. Suppose that a dihybrid plant with coloured flowers in axils is crossed to a pure breeding plant with the same phenotype. What are the genotypic and phenotypic ratios that you would expect in the F1 plants?
