another for kernel shape. These are similar to the loci in pea plants that confer seed color and seed shape.ProceduresExperiment 1: A Monohybrid CrossIn this experiment, you will determine if the distribution of kernel phenotypes in an ear of corn are consistent with color being determined by a single gene that follows Mendelian inheritance.1.Take corn #1 from the Materials shelf and place it onto the workbench. Once on the workbench, the corn will appear in a corn holder that allows you to rotate the corn cob.2.Zoom in to examine the ear of corn. Pay specific attention to the color of the kernels. How many different colors of kernels (different phenotypes) are present on the ear of corn? In your Lab Notes, list all of the kernel colors present in the ear.3.Choose five rows of corn kernels to examine. Count and record the number of kernels of each color present in each of the five rows. Save this data to your Lab Notes.4.Add up the number of kernels of each phenotype to determine the total number of kernelsyou have examined. Save this information to your Lab Notes.5.Discard corn #1 into the recycling bin under the workbench.

Experiment 2: A Dihybrid CrossIn this experiment, you will examine the results of a cross of the F1 generation of corn that has purple and smooth kernels that are heterozygous for both color (P,p) and texture (S,s). The genotype of the dihybrid is PpSs1.Take corn #2 from the Materials shelf and place it onto the workbench.2.Zoom in to examine the ear of corn. Note the color and texture of the kernels. How many different colors and how many different textures do you observe? How many different kinds of kernels (different phenotypes) are present? How many traits are you studying in corn #2? Record the answers to these questions in your .Lab Notes.3.Choose five rows of corn kernels to examine. Count and record the number of kernels of each phenotype present in each of the five rows.4.Add up the number of kernels of each phenotype to determine the total number of kernelsyou have examined. Save this information to your Lab Notes.5.Discard corn #2 into the recycling bin under the workbench.Lab notesExperiment 1: A Monohybrid Cross*This ear of corn is mostly purple in color with a few yellow throughoutRow 1: 30 kernels; 10 yellow & 20 purpleRow 2: 30 kernels; 14 yellow & 16 purple Row 3: 30 kernels; 6 yellow & 24 purpleRow 4: 30 kernels; 5 yellow & 25 purpleRow 5 30 kernels; 9 yellow & 21 purpleExperiment 2: Dihybrid Cross*This ear of corn is also mostly purple with yellow throughout. There is a few with a bumpy texture.Row 1:30 kernels; 8 yellow, 2 bumpy yellow, 20 purpleRow 2: 30 kernels; 12 yellow, 2 bumpy yellow, 16 purpleRow 3: 30 kernels; 6 yellow, 4 bumpy yellow, 2 bumpy purple, 18 purple
