The animals will only recieve the traits that the DNA they recieved encodes. Dutch scientist build one human gene into a cow named Herman the Bull. He was just a normal cow, there was just one single substance his body produced that a natural cow does not.

Scientist have replaced 500 genes in backer's yeast by their human variants. The result were not strange human/yeast hybrids. Just a bunch of healty yeast cells. I can give a hundred more examples, but I think I've made my point.
