In lupine, the formation of alkaloids is controlled by the complementary genes A and L, which are in a dominant state. In the presence of one or two pairs of recessive alleles of these genes in the genotype, plants do not form alkaloids and can be used in animal feed. Consequently, phenotypically the same alkaloid-free varieties can be different in genotype. Determine which genotypes will have alkaloid-free hybrids obtained from crossing plants, one of which is heterozygous for gene A and homozygous for the dominant gene L, and the other plant is diheterozygous.

Alkaloid-free hybrids obtained from crossing plants, one of which is heterozygous for gene A and homozygous for the dominant gene L, and the other plant is diheterozygous, will have genotypes aaLL, aaLI.
