Detailed explanation-1: -Therefore, the presence of atleast one P allele will give purple colour (dominant phenotype) to the flower. Thus, the PP is a homozygous dominant genotype. Hence, the phenotype of PP is purple colour.
Detailed explanation-2: -The different possible genotypes are AA, AO, BB, BO, AB, and OO. How are blood types related to the six genotypes? A blood test is used to determine whether the A and/or B characteristics are present in a blood sample.
Detailed explanation-3: -A plant that has the genotype Pp is said to be heterozygous (HET uhr OH ZIE guhs). square for this cross is shown in Figure 2. All of the offspring have the same genotype: Pp. The dominant allele, P, in each genotype ensures that all of the offspring will be purple-flowered plants.
Detailed explanation-4: -When a “Pp” genotype plant is bred with a “pp” genotype plant, what percentage of the offspring is likely to have white flowers? 50% of the offspring are likely to have white flowers.
