Biology students are striving to learn about genetics and heredity. So far we have conducted 2 labs to promote an understanding of these topics. The first lab was modified from a genetics concept kit. Students used pennies with yellow and green stickers on them to duplicate breeding experiments that were carried out by Gregor Mendel in the 19th century. The pennies, with yellow and green stickers on the faces, were used to simulate gametogenesis and fertilization. Students tossed the coins on the table and recorded the random genotype combination that resulted.
The second lab students conducted allowed them an opportunity to isolate DNA from a cell. This gave students an opportunity to review different features of the cell (including DNA), as well as have the opportunity to see what DNA looks like, and understand how scientists are able to isolate DNA from cells.
