Ok, I am not supporting bestiality here. But, I just came to know about a Dogxim, a dog fox hybrid and I had known for a long time that horses and donkeys can breed (to produce a mule). So, I was just curious, can humans breed with any other animals closely related to us?
An odd pair of chromosomes makes it harder than being off by a pair. Mules are unbreedable due to their odd number of chromosomes.
We have successfully bred with species further apart, including an alpaca and a llama.
So yes all the science points to it being possible with humans, but ethically we can’t possibly do that.
And it is not one more mutation to add an extra chromosome. It’s a loooot more.
