1Heredity II LabObjective 1.Describe the inheritance pattern of monohybrid and dihybrid crosses in Arabidopsis thaliana. Safety2.Closed-toe shoes must be worn3.Long hair tied back4.Goggles must be worn at all times while experiments are being conducted in the classroom. Even if you’re done.5.Gloves should be worn while performing the experiments.6.Green filter goggles must be worn when examining plants under royal blue light.7.All plant material and plates should be placed in the biohazard bag at the conclusion of your experiments.8.Wash your hands before leaving the laboratory.Lab Activity : Heredity in a Dihybrid CrossOrdinarily, you would have sown a number of F2 seeds during Heredity I and would be examining the resulting seedlings this week. You would begin by looking for hairs on the first true leaves using white light and a dissecting microscope, noting whether each seedling has trichomes (hairs) or is glabrous (without hairs.) Next, you would darken the room and use a royal blue light source to illuminate the seedlings. Viewing the seedlings with a pair of green filter glasses, you would note which seedlings are expressing green
