A homozygous plant has sepals of 30-cm flowers while another homozygote of the same species has 40-cm flowers. The F1 flowers are all 35 cm. In the F₂, out of 600 plants the smallest flowers were 30 cm and the largest were 40cm; all the others were of intermediate sizes. If all the genes involved in flower size are additive, how many gene pairs are there?
