Use Figure 14.1 and the following description to answer the questions below.In a particular plant, leaf color is controlled 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 is diagrammed in the Punnett square shown in Figure 14.1, where 1, 2, 3, and 4 represent the genotypes corresponding to each box within the square. Figure 14.1 Which of the plants will be true-breeding?

Five essential steps in meiosis are listed below.1. Formation of four new nuclei, each with half the chromosomes present in the parental nucleus2. Alignment of tetrads at the metaphase plate3. Separation of sister chromatids4. Separation of the homologues; no uncoupling of the centromere5. Synapsis; chromosomes moving to the middle of the cell in pairsWhich of the steps take place in both mitosis and meiosis?
