Hybrids in Thedas?

I meant a literal hybrid. Not just genetically, but physically too.

One shows physical traits of both races and the other only has mixed blood.

Okay - I'll go on a bit of a tangent that isn't targeting specifically you Iddy, it's just that I saw similar sentiment pop-up in different places at different times, and want to spare some time to address it here, given the opportunity.

I'm fairly certain that there's more 'lore from adversity' (like 'we can't make qunari horns in DAO hece we made it so hornless qunari are considered special' or 'The Dragon Age Setting is actually a name of our continent now, lol') in DA than things we already know about, but do find it somewhat irksome that oftentimes story or lore that began its life that way is considered inferior, or even 'lazy'.

It's ironic, because - aside from the fact that creative process is usually messier than it's commonly believed - limitations like this are some of many creators (mine included) favorite problems to solve, or in fact considered to be essential for honing creativity (example? Some of the most memorable movies, like Jaws or Star Wars, had many unique and innovative solutions because they've had to go around many technical or budgetary limitations).

So let's not immediately throw the word 'laziness' or 'it's just lack of resources' around, even if something has indeed began its life as a limitation to go around that they've decided to incorporate into lore.

...With that said, I'm not sure the whole 'no discernible hybrids' began its life that way. Simply because I think they could easily get away with it - the DAO or even DAII elf and human models aren't terribly different and CC can always make the face more elf like or more human-like. If anything, this can always be spelled outright in lore, even if not through visuals. We know now, for example, that both Tevinter and elvhen architecture in DAO was actually just the same Tevene architecture, yet they've used this to their advantage when they wanted to keep things ambiguous (is it really Tevene? Or is it elvhen?) or spelled outright when they wanted to establish something as, say, elvhen.

In other words - even if we assume that right now they WILL have resources to provide us with more body shapes (because I'm pretty sure that there are also more body types for each race than what we got in past games, including more slender/bulkier or curvier/thinner versions for non-mixed races) I don't think the lore will budge much from what was established already.

In fact I suspect its such an integral part of story (in other words: there's more to it than a simple hand-waving of game limitation concerning body shapes) it's why we didn't yet get many answers to begin with, or why the devs are careful with answers now - and that giving us proper explanation as to why things are the way they are probably ties directly to why the world is the way it is after the lifting of the Veil and collapse of Elvenhan.

In other words, they likely can't say much, because it may spoil quite a few things in the story.

Its a curious question to be sure. Though in the case of human/dwarf pairings it does look like the resultant offspring will be human.

I base that off Kieran. In one of my seven worldstates I created a male Dwarf, Demiriz Aeducan who both romanced Morrigan and did the dark ritual with her. Then along comes DAI and Kieran looks like any other run-of-the-mill human boy. Exactly the same as he looks like in my other male Kylen Mahariel based worldstate who, although he didn't romance Morrigan (Leliana instead) he did do the dark ritual.
