In snapdragon, the gene for red color of flowers (R) incompletely dominates over the gene for white color (r), so that heterozygotes (Rr) have a pink color of flowers; the gene for wide leaves (B) incompletely dominates over the gene for narrow leaves (b); therefore, in heterozygotes (Bb), the leaves have an intermediate width. What will be the color of flowers and width of leaves in F2 from crossing a plant homozygous for dominant genes with a homozygous recessive?

cleavage by phenotype will correspond to cleavage by genotype, i.e. 1: 2: 1: 2: 4: 2: 1: 2: 1.
