I'm pretty sure that's not even possible. Human male sperm can not fertilize a female animals eggs and male animal sperm can't fertilize a female humans eggs. Or at least we haven't really found any animal to crossbreed humans with. If it were possible the outcome could vary.
That is both impossible and illegal. First DNA doesnt match. Cross species pairings dont work genetically. Humans cant even cross breed with their closest genetic match, the chimpanzee. Second ewwwwwwwww!!!!!!!! For that to occure someone had to commit beastiality - sex with an animal! Highly illegal and DISGUSTO!!!!!!! In fanatsy and myth like with shape shifters it simply results like any cross breed. Characteristics of both parents with varying results. In real life cross breeding of similar but separate species the results are almost always an inability to reproduce. Sterility. The mule is a cross between donkey and horse. Mules cannot reproduce. Ligers and Tigons are a cross between a lion and tiger. Again they cannot reproduce.
Let me guess, you would have evolution? (That is, you are taking 2 different species to make a baby, while I understand that from the definition of species, and all the comments above that it is genetically impossible. Just give it millions of years - and you still won't have it.)
