Just wondering but is it possible for 2 races to breed and make half children
and if unknown sould this sorta thing be added?

Yes, all men and mer can freely interbreed. Khajiit might be able to breed with other races - a normal sixual intercourse is possible, it's just uncertain if they're fertile with non-Khajiit. Argonians are an open question, we know too little about their physiology.

Usually the offspring will be the same race as the mother, with some features inherited from the father.

Here's the only book that tries to anolyse this issue:
http://imperial-library.info/content/notes-racial-phylogeny-and-biology

Also, the entire Breton race essentially began from a union of Elves and Men: the Aldmer and the Nedes, respectively.

Also also, that took centuries of interbreeding (mothers with some father traits and on and on). So it's not an instantaneous half breed thing.

Children of mixed races'll inherit the race of the mother with some traits of the father showing through. Case in point; a child of a male Dunmer and a female Redguard would have a slight grey pallor to their dark skin and elven features like high cheekbones and almond-shaped eyes, but it'll be a Raga Da through and through with a love for adventure and sword fighting with maybe some love of blowing things up thrown in.

Now there are mixed races like the Bretons and maybe the Bosmer, but it takes many generation of interbreeding for that to happen.

This book doesn't know if Orcs can breed. Yes, they can! You get to see a half-orc in Oblivion. He looks like a normal Orc except for white skin like a human. But it turns out his dad was a Vampire, so I do not know if the pale skin is a vampiric or human trait.

I think Lord of Souls might of touched or hinted upon the subject of argonian / other race breeding. Although it's been some time since I read the book.

That's all cultural stuff. There is nothing in a Redguard's genes that says "You must love Sword fighting" Same with the magic side. It depends on where the child is raised.

ok well what if we went a little further? say a creature who wasent apart of the main races
like a giant or a werewolf in werewolf form?

Giants no I doubt that could happen. The reproductive organs don't really fit ya know.

I remember reading somewhere that Lycans can pass the curse on to their children, but I don't think they have six in werewolf form. I'm not saying they can't though. Just that they probably wouldn't since that's not what their lord wants them to do when they change. In that form its all about the hunt.

The book still gives the general idea how interbreeding in TES works. The first paragraph is quite a good summary of what we know at this point (except the part about Argonians' classification). The rest is assumptions and theories, so obviously I wouldn't consider it decisive evidence one way or the other.

I know about the Gray Prince. I always thought it was natural that orcs were fertile with other races - they're still mer, after all - but it was nice to find out that vampires can breed too.

As for werewolves, my guess is that they could reproduce with other wolves while in their wolf form, similar to how they're fertile with humans in their human form. I wouldn't count on a human-wolf pairing, it's probably like with a regular wolf, meaning it won't work. But I know next to nothing about werewolves, so don't take my word for that.
I actually like the idea that they only do Hircine's bidding when in the wolf form. If so, then infecting others with lycanthropy would be their way of procreation, right?

That's how it works in the real world, sure, but also: in the real world, race is pretty much a false term.

In Tamriel, we know for certain that some races live several times as long as others, some have fangs, and some can breathe underwater. It's entirely possible (near-confirmed by old racial abilities) that the Raga produce adrenaline in a different way from all the other races and that this leads to their love of adventure and melee fighting. Maybe the part of the Dunmer brain that processes schadenfreude is far more developed, and so they're more naturally inclined to enjoy destroying things and harming others.

Racism is complete and utter BS in real life, but Tamriel isn't real life.

Weird thing about the gray prince is that he seems to support Lamarckism.

Since Vampirism is based off the disease Porphyritic Haemophilia, I think it is more like how babies inherited syphilis from their parents.

But the Prince isn't a vampire, he just exhibits certain vampiric characteristics.

Who the hell knows how that disease works.

Dumac Dwarfking was often called the dwarf orc, but whether he was a halfbreed or the lable is an alliteration is debatable.

The Nords called him Dumalacath.

Yet Redguards are described time and time again to be naturally born warriors with very strong constitutions. Their builds in all ES games make them prime warrior builds. This isn't the real world where race is just a term used to erroneously stick people in groups that just so happen to have the same skin tone or nose size. Races in the Elder Scrolls do have natural predilections towards certain fields.

I think the whole Redguard-warrior thing is a little bit of both culture and genetics. They're a warrior culture, so most likely anyone raised in that culture is going to be influenced by it. They're also naturally hardy and agile, and have that fierce warrior spirit and pride bred into them. So, for instance, a Breton born into Redguard culture would probably be a better warrior than homeland Bretons because he was exposed to that culture, but he would still lack the Redguard "warrior genes."

Conversely, a Redguard raised in High Rock would probably be more inclined towards the arcane (or politics?) because of culture, but wouldn't have the natural affinity for magic. He would still have that warrior spirit in him somewhere.

And if you put the two together, you would get a Bredguard......

It's a daedric curse, that alone should be enough to have an idea of what it'll do.

http://youtu.be/fk-n9qMP1UE?hd=1. That is what "dwarf-orc" amounts to.

"That's how it works in the real world, sure, but also: in the real world, race is pretty much a false term."

Of course your right. I should have said ethnic group. The culture part is still accurate though.

As for the second part I have to disagree. The Nords use to practice magic but for one reason or another it fell into disfavor. Same with Redguards, though with them I think we have a good reason as to why they turned from it. Both groups turned from it for cultural reasons.

I just want to stress the point that culture plays a large part here. If Certain "Races" were predisposed to fight a certain way then wouldn't all mer favor magic since that's what their ancestors fought with? When looking at the lore we see that is clearly not the case.

Yip. http://images.uesp.net/d/de/OB-clutter-Giant.jpg

Nope. http://images.uesp.net/d/de/OB-clutter-Giant.jpg

Image is way too small. Care to explain it, or get something larger.

It's a family tree that features a giant man and a normal sized woman as a mating pair. It's apparently part of a ditched quest from oblivion that would involve a man who thought he was the descendant of ogres. They try to eat him.
