We learned something new that we want to pin here! In our location, the blood type without A or B antigens is written as letter "O" pronounced "oh." But in many countries, it's written as zero "0" called zero/null.

I don't really comment on videos but I just wanted to take the time to say thank you amoeba sisters. Your videos helped me refresh biology concepts that I have forgotten since I graduated college. Thanks to your videos, I passed my biology praxis exam so thank you.

Months ago I watched all of amoeba sisters’ videos just cause. Never did I think that I will choose Biology as my major in college but here I am now. I just wanted to say thank you. Your videos really helped me grasp and understand the concepts easier!

Why can't you be my biology teacher??? 😕😢

These vids are pretty darn awesome! My biology teacher has been showing these vids to introduce us to new topics, keep em coming! Really enjoying these cuts lessons ^^

I'm getting ready for my Science Field Day and I needed to learn about Heredity for it. I was really scared till I found this playlist, you guys saved me and my team. You make complicated concepts seem oversimplified and easy to learn. Thank you so much!

I'm here as a college genetics student. Really appreciate the presentation of this content. I know it's probably not aimed at me but it is hitting where it needs to. Thanks.

I’ve been sick almost all week and I’ve got an exam in my AP bio class the day after tomorrow and you just saved me. You ladies are doing an amazing job, I wouldn’t know what I would do without you guys! 😅☺️

Love your graphics style! They are adorable and educational.

I love the Amoeba Sisters! Always informative and helpful. I am in college and I'm not ashamed to say that these videos have helped me study for tests. Thank you sisters! Stay cute and adorable! <3

The genetics part starts at roughly 3:30 mins.

[neileoZz]

these animations are just great, it really makes science less boring and keeps me from completely zoning out xD

[poolcezanne]

Great! ... I learned more from here than my paid teachers. Really!

[thenhewonders]

Thanks so much, Amoeba sisters :D

I was reading this in my textbook and I was totally lost.

Then I checked your channel, found this great video, and it all made sense!

:)

I am thrilled to see that you got every content I find difficult in my syllabus. The best part is I can totally relate and understand you. Wish I found you earlier. Love you😍

[damiouschic]

you guys do great job. I love biology and even if I wouldn't, you would have helped me get to it for sure!!! keep going💟

[dailydoseofunease]

My bio teacher always recommends us to watch your videos and now I understand why, thank you so much because all the topics are super clear and the videos are fun!

Ty Amoeba Sisters! As a visual learner and non-native speaker, your video had helped me tremendously! Compared to the biology videos on youtube that I have had watched, you guys videos are the easiest to understand and yet fun to learn!
