A 2n=4 plant is heterozygous at two genes, one controlling plant height (T = tall, t= short) and one controlling disease resistance (D = resistant, d = susceptible). The plant height gene is located on one chromosome, and the disease resistance gene is located on the other chromosome. In the cells below, draw to two possible arrangements of the chromosomes at metaphse I of meiosis. Hint: look at Figure 2.17 in your textbook for an example of how chromosomes can be arranged at metaphase I. Be sure to label the alleles present at the genes on the two chromosomes in each drawing.
