Imagine that height in corn plants is determined by three loci. The baseline height is 100 cm. Every + allele adds 10cm to the plant’s potential height, every – allele subtracts 10 cm from the plant’s potential height. The shortest possible plant and the tallest possible plant are mated to form an F1, what is the height of the F1?
