    Okay so, mammals have sperm and eggs. Humans are mammals. Example, pigs are mammals.

    In theory, wouldn't it be possible to cross a human and a pig?
    Unless there are specifics for the sperm cell of an animal?

    If you can do it with different breeds of dogs (not much of a difference between each dog) and that works, it should work with other species. No?

    Any help would be great. I've been pondering this for years. Never got around to actually saying anything.

    Yes, It is possible. However the fetus will not make it past the first week, due to extensive differentiations in chromosomes. First week, because all mammals are chordates and start of the same. It does not matter about the phylogeny of mammalia, it matters about the species and their chromosome structures. Your comparison among dogs is like Asian and Blacks nationalities among humans.

    Yes. Dogs and even wolves are essentially the same species, but they are more removed from each other than humans are.

    AFAIK, chromosome number might be an obstacle and even if a functioning hybrid can be achieved, they will most likely be sterile.

    You can, of course, transfer genes from one species to another, even if the greenie world is opposed. That is the closest you will get to a true hybrid, except between very closely related species.

    Another factor to consider is whether or not sperm and egg are able to communicate with one another and initiate membrane fusion. There are sperm receptors and egg binding proteins, for example, although I don't know how fussy they are between closely and/or distantly related species.

    That picture you presented is 100% fake. It is not at all possible to achieve a human/pig baby. It is like saying bird/human baby. The chromosome are so different that it is out of question. Here is the proof that the picture is fake.

    I don't think anyone here was entertaining the authenticity of the pic :-)

    Still, it's probably a good thing that you posted that link since there will invariably be someone stumbling on the forum from Google et al that might not possess critical thought processes or sufficient understanding of mammalian reproduction to recognize the pun.

    By the way, as an illustration, your image of the glycolytic pathway is cool. But as a signature it's a little much. We don't have a lot of rules and restrictions on signatures and avatars, and we haven't, as yet, established a size restriction on signatures, but yours might inspire it.

    Think of it this way: large signatures take up a lot of space in a thread and increasing numbers of members are using things like iPhones and Blackberrys to browse the forum.

    Thanks for the consideration I know you'll have, and Welcome to The Science Forum. I like the screen name you chose.

    Thank you so much. I understand, I will try to find a complementary picture. Thank you for letting me know.

    This has already been addressed in the thread- the photo was not being presented as authentic. Jazzy- this thread has not been updated in a month. It is considered rather bad form to resurrect a thread that has been inactive for some time unless you have something meaningful to contribute. In this thread and others that you have bumped from months back, you have not made useful contributions. I hope that you will not make a habit of this.
