There was always a hint of sexual tension between Tali and Garrus, so maybe Quarians and Turians have compatible physiologies?

And Turians don't appear to have mammaries!

[Askold]

Or, maybe they were just romantically attracted despite being biologically non-compatible.

(I don't remember any references to cross species breeding in Mass Effect other than the Asari reproduction-weirdness.)

[Tolpuddle Martyr]

True.

You can be romantically attracted to Garrus and be human, and we know they aren't biologically compatible.

So there is that.

Turians and quarians are both dextro-amino based species, so they're probably more compatible with each other than anything else. I don't think a turian-quarian hybrid is possible but if the quarian's shitty immune system is compensated for I don't see any obvious reason why they wouldn't be compatible. I'd even go so far as to suggest the possibility of a common evolutionary origin - they've got the exact same "doglegs", similar hands, etc.

The Salarian and Krogan have the same dog legs.don't they?

Krogans don't, their knees bend forward. Salarians have backwards knees too but the proportions are different and they lack the bony spurs on the back of the legs.

Maybe it was a panspermia scenario?
