Two genes in tomatoes are 61 mu apart; normal fruit (F) is dominantto fasciated (flattened) fruit ( f ), and normal number of leaves(Lf ) is dominant to leafy (lf ). A true-breeding plant with normalleaves and fruit was crossed to a leafy plant with fasciated fruit.The F1 offspring were then crossed to leafy plants with fasciatedfruit. If this cross produced 600 offspring, what are the expectednumbers of plants in each of the four possible categories: normalleaves, normal fruit; normal leaves, fasciated fruit; leafy, normalfruit; and leafy, fasciated fruit?
