Inquiry Lab: Genetics in the Garden Warm Up: Connecting Previous Ideas from Meiosis “T” is a dominant gene that represents “Tall” “t” is a recessive gene that represents “Short” What will each baby plant look like when dad’s sperm joins with mom’s egg? Tall T + T = TT ?_________ t + T + t + Short ?_________ t = tt t Tall = Tt ?_________ T Tall = Tt ?_________ Introduction Gregor Mendel was an Austrian monk who lived in the mid 1800s. He spent most of his time in the garden where he took care of pea plants. Mendel wondered how plants inherited the trait of height (tall or short) from their parents. To find out he conducted experiments over many years. He mated mother plants and father plants to observe how the offspring (baby plants) would look. Question to Explore You will simulate Mendel’s experiments. Instead of real plants, you will use pennies to represent the mother and father plants. Each penny has two sides because each parent has two genes. However, a parent can only pass one gene (one side) to their child. You will simulate this by flipping the coin. By conducting the experiments on this lab, you will be investigating the following questions: – How are traits passed from parent to offspring? – How does chance play a role in inheritance? TO DO! As you complete each step under the procedure please check it off. – Complete Steps 1-21 in class! – Complete Step 22 for Homework! Closure: Let’s Recap P F1 Experiment 1 ? = All Tall! Experiment 2 F2 ? = ¾ Tall & ¼ Short!
