In а pаrticulаr plant, leaf cоlоr is cоntrolled by gene locus D. Plants with at least one allele D have dark green leaves, and plants with the homozygous recessive dd genotype have light green leaves. A true-breeding dark-leaved plant is crossed with a light-leaved one, and the F1 offspring is allowed to self-pollinate. The predicted outcome of the F2 offspring is diagrammed in the Punnett square shown above, where 1, 2, 3, and 4 represent the genotypes corresponding to each box within the square. Which of the boxes marked 1 - 4 correspond(s) to plants with dark leaves?
