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: https://www.youtube.com/watch?v=fcGDUcGjcyk&list=PLwL0Myd7Dk1FVxYPO_bVbk8oOD5EZ2o5W
This video has a handout! http://www.amoebasisters.com/handouts
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: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3349222/

The Amoeba Sisters videos demystify science with humor and relevance. The videos center on Pinky's certification and experience in teaching science at the high school level. Pinky's teacher certification is in grades 4-8 science and 8-12 composite science (encompassing biology, chemistry, and physics). Amoeba Sisters videos only cover concepts that Pinky is certified to teach, and they focus on her specialty: secondary life science. For more information about The Amoeba Sisters, visit:
We cover the basics in biology concepts at the secondary level. If you are looking to discover more about biology and go into depth beyond these basics, our recommended reference is the FREE, peer reviewed, open source OpenStax biology textbook: https://openstax.org/details/books/biology

Ups ups m sorry , now my doubt has been cleared after seeing video again actually i got confused with the diagram or the picture of the pair of chromosomes just assuming it as one single chromosome😝😝😝😝
Just confused with the fact that are the alleles present on the homologous chromosomes , i mean on non sister chromatids or if they are present on the sister chromatids but i think that they shud b present on non sister chromatids and at the same locus as u said but in the video they are show on sister chromatids , so lil bit confused😓😓😓
Oh my gosh! I had to stop the video and re-evaluate my childhood. You have the same exact PTC horror story as me! I felt so out of place, like I was missing out on an opportunity. LOL one classmate tried to cheer me up by also telling me i should be happy I can't taste it even trying to describe the taste to me, but i didn't feel any better either.
Came here to tell you that both of you wonderful people have done me wonders. Helped me understand complex things in 9 - 15 minutes, when my teacher lectures us all day (knowing that no one listens) and tests us on unfair crap we don't know. Thank you for everything, please keep this up for future students.
Hey Amoeba sisters!! I'm a freshman in biology and your videos have helped me so much! I would love it if you could make more bacterial videos on chemoautotrophs, heterotrophs, decomposers, etc. I just find it all very confusing and you guys always seem to make everything so clear! Love you guys!
Hey Sisters I learned a lot from your videos but the thing is that i really need to understand the topic "Gene regulation during development" i searched out each and every ppt , videos , lectures i didn't understood a thing.My only hope is you now as i have to submit my assignment before february.If you can help with this topic asap pleaseeeeeeeeeeeeee.
You guys are the absolute best! Yes, I'm in tenth grade, and I still get back to your videos whenever I need help with Biology! Oh, how I wish you guys could do Chemistry as well! That'd be brilliant. Lots of love <3
