Wrinkled and Round Peas—Determining Their Genomes Introduction : This lab is designed to help students understand what phenotype and genotype are and the difference between the two based on experiments relating to those of Mendel. Mendel believed that pea’s were wrinkled or round based on their phenotype because of different sugars, starches, and seed sizes. Although today it is known that a pea’s shape is based on its genes, we will be conducting these experiments in three parts in order to understand these features as we observe them for ourselves through experimental design. This design consists of determining the phenotypes of three different types of peas, assigning these peas genotypes using these data, and explaining the reason as to why Mendel’s peas wrinkle. This experiment data will be based on the findings of sugars and starches based on the different shapes of the peas, and also the differences in these different pea types’ starch metabolism. Materials and Methods : In this experiment we will deal with three different types of peas, one round and two wrinkled. These types will be: Alaskan (round), Mr. Big (wrinkled), and Little Marvel (wrinkled), and we will use four peas of each type. When staining the pea mortar in experiments 1 & 2 we will use 10% Iodine, and then proceed to sketch what is viewed under the microscope as data important to this part of the experiment. Results
