A  strain of grain has variation in oil content . Diploid grain oil content is influenced by four genes (A or a through D or d) with two additive alleles each. Each of the genes contributes equally. The highest-producing strain has 24% oil content; the lowest has 0%. Which of the following genotypes would have on average 9% oil content?
