Assume that three loci, each with two alleles (A and a, B and b, C and c), determine the differences in height between two homozygous strains of a plant. These genes are additive and equal in their effects on plant height. One strain (aabbcc) is 10 cm in height. The other strain (AABBCC) is 22 cm in height. The two strains are crossed, and the resulting F1 are interbred to produce 1000 F2 progeny. what is number of F2 progeny having intermediate height?
