The position of the flower on the stem of the garden pea is governed by a pair of alleles.
The position of the flower on the stem of the garden pea is governed by a pair of alleles. Flowers growing the axils (upper angle between petiole and stem) are produced by the action of the dominant allele T, those growing only at the top of the stem by its recessive allele t. Colored flowered are produced by a dominant gene C, and white flowers by its recessive allele c. A dihybrid plant with colored flowers in the axils is crossed to a pure breeding strain of the same phenotype. what genotypic and phenotypic ratios are expected in the F1 progeny?
