Keep it alive to have an almost griffin

And reproduce its genetic code to make more

Probably not a germline mutation, looks like a signal pathway mutation that happened in the embryo

How can you tell?

I’m taking a developmental biology course right now and am genuinely curious

This article goes into really good detail about the signaling molecules and their significance in interacting with each other in limb development:

Nerrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrd

Thanks

Because it’s localized to one segment. Could be a gap gene or hedgehog problem

u/akrebsel 29d ago

Ah okay thank you

So it’s kind of similar to Ultrabithorax in drosophila?

u/ElSapio 29d ago

Exactly! I could be wrong though, I was more into molecular biology

u/akrebsel 29d ago

Okay cool, maybe ill do some research on it

Thanks a bunch though, I appreciate your insight!

I'd guess hbox, based on the similarity to bicoid (but in reverse).

It's a chicken, not a hedgehog

A lot of pathways in early embryo development affect symmetry and how poles in the embryo are formed.

When you have repetition of segments or structures you have an indication that one of those pathways failed.

I don't know if this helps because i'm not a biologist, but as someone who has worked on a chicken farm, if something goes wrong during the brooding, it's gonna affect the chick's legs first, almost everytime. Tho to be fair i've never seen it add or remove full limbs, they tend to just get weird orientations, but it could have something to do with it too 🤷‍♂️
