I'm a stem cell biologist and I can tell you that organoids have changed my field of research. As explained in the video, we make organoids by providing stem cells with different molecules so that they undergo certain aspects of development. For example, we can make brain organoids which mimic parts of the brain (I made a video about them). Brain organoids are tiny and not as complex as real brains but they help us to understand brain diseases and have recently been used to explain how schizophrenia arises!

I always figured it was waaaay more complicated that the good ol' 2x2 punnet squares

Make senses because of all the different shades of hazel eyes out there.

I feel like they specifically mentioned The Fault in Our Stars because Hank Green is John Green's brother

people who got them tricolor iris OCs on tumblr: my time has come

[Kayclau]

If I could remember who was my biology teacher, I would rub this video in their face because they told me that what they taught me was accurate and my concern about shades of eye color wasn't real.

Shouting out his brothers book was so cute

[medusianAllure]

I'm mixed Eurasian. I have hazel eyes despite my mother having dark brown eyes and my dad has blue eyes. Never understood why when I learned genetics in biology years ago.

So, the first artificial human we create will be able to cry. Good!

[iafozzac]

My eyes have green, blue, and light brown in them. Usually they just look grey unless you're really up close, but, depending on lighting they can look green, blue, or even hazel

In my undergrad biology courses back in the early 90s we were told that eye color was complex and non-Mendelian in nature.

Leslie Fish once posted some of her own research into the genetics of eye color and coat color in domestic cats, and it's ridiculously complicated. (Including why only female cats can have tortoiseshell fur coloration.)

[sleekoduck]

I knew the DNA sites needed more work a few years ago. GEDcom said I had green eyes. Mine are amber. Those are both rare colors, but there's a huge difference between the two. I'm glad to hear that they're discovering more alleles.

Love the shout out to your brothers book!

[meetaverma]

At first I thought it said we found new eye colors. I'm a little heartbroken ☹️☹️

[GaasubaMeskhenet]

My eyes are blue with light light brown in it.(Central Heterochromia) Makes them look gray in some light for some reason. Usually don't know what to put on forms or use on doll makers where I can only pick one color

[nebuloushammer]

In my family, we have completely different eye colors. My mom has brown eyes, my dad has green eyes, my brother has blue eyes, and I have hazel eyes.

[TheZiiFamily]

My eyes have a darkish grey blue outer ring, pale yellow with a red orange flare around the pupil
I just say my eye are a solar eclipse

[monicaenns]

My broad family has a tendency to make blond and blue eyed babies that turn into brunettes with greens and hazel eyes. Except 1 who was born brunette and blue eyed, and grew to be blond and blue eyed!

Wow! The old phrase cry me a river suddenly has a whole new meaning.
