Wild type blue-eyed Mary has blue flowers. Two genes control the pathway that makes the blue pigment: The product of gene W turns a white precursor into magenta pigment. The product of gene M turns the magenta pigment into blue pigment. Each gene has a recessive loss-of-function allele: w and m, respectively. A double heterozygote is cross with a plant that is homozygous recessive for W and heterozvaous for the other gene. What proportion of offspring will be white? O 1/4 O 1/8 O 3/8 O 1/2 Data Acc

recessive for W and heterozvaous for the other gene. What proportion of offspring will be white?
