Bellflowers can have blue or white flowers and can occur as tall or dwarf plants. The chart below shows four crosses between various bellflowers of unknown genotype. Write the dominant allele for each of the two traits and define gene symbols. Write the genotypes of the parents from Cross 1 using your symbols from A. Write the genotypes of the parents in Cross 2 using your symbols from A. Write the genotypes of the parents in Cross 3 using your symbols from A. Determine the genotypes of the parents in Cross 4 using your symbols from A.
