Assume that the length of wheat leaves is controlled by three loci, each with two alleles: l and l, w and w, h and h. determine the differences in leaf length between two homozygous strains of wheat. assume each allele contributes equally to the length of the plant leaves. one homozygous strain, ll ww hh, has leaves that are 100 mm in length, and the other strain, ll ww hh, has 220 mm leaves. the two homozygous strains are crossed, and the resulting f1 are selfed to produce f2 progeny. what length will the leaves of the ll ww hh genotype plant be?
