Chick with genetic defect

[u/Significant_Snow_718]

And reproduce its genetic code to make more

[u/ElSapio → u/Miesnieks1171]

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

[u/akrebsel → u/ElSapio]

How can you tell?

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

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 🤷‍♂️
