For 2 flowering plants : Cross two heterozygous parents (use a punnet square / use the scrap paper provided if needed)      *incomplete dominance applies here. *dominant characteristic = red flower color*recessive characteristic = white flower color – – – – –  Based on the above cross, evaluate the following two statements : determine the best option indicating each as true or false I- Both parents had pink flowersII- if these parents produced 4 offspring (one with each of the genotypes in the punnet square), 3 different phenotypes would be expected from these parents
