Flоwer cоlоr in а certаin plаnt is determined by two independently assorting genes, B and D. The dominant B allele allows a pigment precursor to be converted into a blue pigment. Without this conversion, the plant is white. The dominant allele D causes the blue pigment to degrade and the resulting phenotype is white, whereas the recessive allele d has no effect. A true-breeding white (bbDD) and a true-breeding blue parental strain were mated. If the F1s were then crossed, what portion of the F2s would you expect to be white?
