Blue petal plant(B- has a genotype of BB) + White petal plant(W- has a genotype of WW) --- cross ---> Orange petal plant (unusual third phenotype which is orange)
Work out the genotype of the third phenotype:
When the blue petal plant reproduces with the white petal plant, it contributes one allele each. The heterozygote must be BW but generates a third, different distinct phenotype = CO-DOMINANCE
Both alleles B and W contribute to the phenotype and gives off the orange colour in this case.
