Plants with blue flowers (B) are dominant over plants with white flowers

(b). You cross a plant with white flowers (female) with a plant with blue flowers (male) that is heterozygous. Use a Punnett-square to determine the expected genotype and phenotype ratios of the offspring and answer the following questions:
(1) What are the genotypes and possible gametes of the P generation plants?
(2) What is the genotypic ratio of the F1 generation (include genes)?
(3) What is the phenotypic ratio of the F1 generation (include flower color)?
