I feel dumb for asking as I forgot everything from biology...but does that actually work? Sticking human sperm inside a chicken egg?
Yes, but the animal won't live, I’m pretty sure this is illegal. As you can imagine that’s not really something we want to be experimenting with for ethical reasons. If that goes wrong and we create something bad then whoever did the research would be in a lot of trouble.
Even if it wasn’t illegal (I think), two species have to be very closely related to breed. So a horse and a donkey can breed because they have very similar genetics. But a horse and a cat can’t breed because they’re so different. Dog and Human DNA is so different that you wouldn’t be able to mix them together
