Learning About Genetics
My students are in the process of learning more about DNA and Heredity. We started our unit off with a lab activity that simulates gametogenesis in pea plants. In one class period we modeled what it took Gregor Mendel 40 years to complete. Unfortunatly we were so involved with collecting our data that I forgot to take pictures. However, today we are going to simulate how sexual reproduction can lead to genetic variation within one family. Students are modeling meiosis (using 14 chromosomes), and fertilization of a zygote. We will have plenty of pictures to share from this activity.
