We like to address clarifications or corrections in our videos in the pinned comments. Pinky accidentally said "coefficients" at 2:10 when she should have said "exponents." These are exponents as shown in how the sex-linked trait was written at that time stamp. We greatly appreciate the individual who let us know this was in the video! :D

My science teacher is so obsessed with the amoeba sisters that she has a custom dress with them on it, and makes us watch and answer questions on wednesdays and dedicates the whole the day to it. I can’t lie I’ve formed an addiction

[burkleyboo]

I’m glad the Amoeba Sisters are getting more famous due to online school. They deserve the fame!

[jrseahorse]

Every time they say pedigree I think of that pet brand food 😂

[akiMin_lover]

I was crying a while ago because I'm in 10th grade and we were given a case study that includes a very complex pedigree chart but now I'm all cheered up because it was that easy😭 thank you so muchhh

[DudeZapatoChevy]

I was very reluctant at first when my teacher included links to videos on youtube, but you guys are actually hella funny (I love all the references) and you're VERY clear about how things work. Thanks!

"Pause the video here" Literally 2 nanoseconds later "*Shows answer* OK howd you do.

[JackelineMcGovern]

The Amoeba Sisters are the only ones getting me through my cell bio class in my first year of college. I love them and their humor so much.

[staycalm]

A knowledgable official biology teacher and her creative minded sister who makes learning fun by creating hilarious cartoons, both of them together created a series of biological videos which deserves high appreciation from everyone. Hats off to you two.

This really helped my Freshman son who is learning about genetics.

You guys not pushing the video to 10 mins to get the extra add shows your intention of truly teaching, and not getting the money. I respect that

[backstreetfan]

Amoeba sisters can make any topic even more fun and interesting.
I loved the "My what a mysterious genotype you have Grandma" part and also the part with Captain Picard.

I was drinking milk while watching this, and at 5:20 I laughed so hard I spat it all over the screen! Very funny and nice video. I watch all of your new vids and have been a subscriber since my biology teacher started showing your videos in class. Thanks for the helpful videos! Keep up the amazing work. Love you guys ✌

I love it! And - gotta share real quick - when the nurse at the hospital told us that our youngest daughter's bloodtype was O negative, I exclaimed (with a large amount of enthusiasm), "That means that we know the genotype for both of our blood types!!" and then explained to my husband how this was proof that he (being O positive) was heterozygous for the Rh factor, and I (being B negative) was heterozygous for the B allele. The nurse looked at us a little strangely and said something about O neg being the universal donor -- and we were like, "Yes, yes, that's very cool too. But we're basking the joy of a genotype/phenotype discovery here!"

Thank you so much for continuing making these videos! They're always helpful and always seem to come at a great time for me! In my 6th semester of college and you're still saving my butt!

[vidushisingh]

The way you explain these topics is so simple and understandable that it blows my mind!! I really don't know how my teacher makes everything sound so complicated! You have really helped me for the past 2 years!! Keep it up!

[davythang]

my science teacher show us your video because he say he's terrible at explaining and he's boring

[MikaylaAriel-ne]

My bio teacher always had us watching the Amoeba Sisters on Edpuzzle. These videos are 10x easier to understand than when my teacher actually teaches it herself. I'll just let the Amoeba Sisters be my teachers from now on. They deserve way more recognition 💙 Keep up the good work sisters!

These are so cute and funny! I am so happy to have stumbled upon this. Honestly, a huge blessing because I am extremely right brained and anything that doesn't interest me or I can't memorize or relate anything to is ridiculously hard for me to understand... But cartoons that are smart and funny help me immensely! Thank You!
