The Perfect Pair of Genes!



Why are your eyes that color? Where did your facial expressions come from? What traits could you pass on to your children? The conversation begins here as we create a larger-than-life chromosome model to focus on genes and genetic traits. With a fun play on words, jeans and other clothing items are used to represent genes on giant chromosomes. Students tap into previous knowledge about DNA, explore the large chromosome models in their classroom, and investigate the important role genes play.
