Alleles and Genes

Join the Amoeba Sisters as they discuss the terms “gene“ and “allele“ in context of a gene involved in PTC (phenylthiocarbamide) taste sensitivity. Note: as mentioned throughout video, the ability to taste PTC may be more complex than a single gene trait. This video serves as an introduction before exploring Punnett squares in our heredity series: This video has a handout! While this video only focuses on basic understanding of alleles and genes as well as the ability to taste- or not taste- PTC (phenylthiocarbamide), we encourage learning more! Here is a recommended reading that expands on the genetics involved in tasting PTC and includes some of the history in how it was discovered: The Amoeba Sisters videos demystify science with humor and relevance. The videos center on Pinky’s certification and experience in teaching biology at the high school level.
