In science, we are learning about heredity, genes, DNA, and traits. We've been learning about lots of these things in science class. We did this experiment on ourselves to see if we had a certain gene. It was using PTC strips. They are pretty much just paper strips sprayed with the PTC chemical. We all put our own strip in our mouth at the same time. If we tasted it, we have the gene that made it taste BITTER. I personally didn't taste it, but Cameron sure DID! Within seconds his face was super red. He was very disgusted from the strip and he said that he was almost crying. We also looked for other genes in ourselves like hair type, eye color, and earlobes. After that we did a bar graph on all of the traits in our classroom. What did you guys think about the PTC experiment? (By: Leif P.)
