For this question, you will have to do a cross like those found in the Mendelian genetics exercises. Suppose that Mendel did a cross between plants that varied in the color of the flowers of the pea plants. Some were purple and some were white. He first created true breeding lines of the two forms. He then crossed them to form the first offspring generation which were all purple and had the genotype Pw. What would happen if he back-crossed Pw and the original true-breeding white line? Provide both the genotype and phenotype ratios of this cross. You must label your answers. If you try to describe your work and you are wrong, you may still get partial credit.
