Punnett squares practice 10. in four 0'clock plants, the dominant allele for the flower color is red (f), and the recessive allele is white flowers (f). flower color in four 0'clock plants is also a incomplete dominance,which means when the organism is heterozygous (ff), the dominant and recessive allele blend to make pink. if one white flowerd plant and one pink flowerded plant are crossed, hat will be all the possble genotypes and phentoypes of the offpring
