How do you know this?
It's right there in the codex and even the bartending matriarch backs it up. The children of asari/alien unions do not inherent ANYTHING from the alien partner. Nothing.
If you pay attention to Liara's conversation in ME1, even she doesn't seem to buy it. She explains the whole traits-from-father-species notion, but then immediately says that's what "popular wisdom" claims.
I am pretty certain that "or so conventional wisdom would hold" only referred to nothing being gained from Asari-Asari melding.
Yeah, I know. But that's the point: if Liara doubts the notion that nothing is gained in A-A bonding, then she also necessarily doubts the notion that aliens contribute anything new. Why? Because the only justification ever offered for out-species bonding is the belief than in-species bonding is inferior. The two ideas are inextricably linked in Asari culture.
The Asari are the oldest citadel species, so following Bioware's idea that a race becomes more and more homogenous with time, doubting if A-A melding gives something new, simply means doubting how homogeneous the Asari already are.
No, it doesn't. Why? Because no asari
ever says anything remotely like that. In fact, Mordin is the only character to even bring up genetic diversity. The asari
always talk about the belief that the father actually contributes to the child, and it's
always contrasted with A-A pairing.
Also, there's nothing in the games that says all races necessarily become less genetically diverse over time. They simply are less so than humans, and no reasons are given. However, it's not at all difficult to see why this is so in many cases:
Asari: parthenogenetic, single genetic parent. They also have very long generations and aren't known to be especially prolific breeders.
Krogan: nearly went extinct after genophage. Massive bottleneck resulted and there's been continual genetic attrittion ever since as krogan males keep leaving and end up dying without having children.
Salarians: species is 90% male, and very, very few of those males will ever take part in a mating. I.e., the bulk of novel mutations in any given generation are just thrown out.
Drell: another massive bottleneck as most of the species died a few centuries back, and relatively few were evacuated.
Quarian: huge bottleneck again, thanks to the geth killing all but a few million of them 300 years ago. Only 17 million currently exist, and they live in shielded ships and wear those suits all the time. The piligrimage tradition also inflicts some genetic loss, though it likely hasn't been long enough to have any real effect on overall diversity, and some of those who don't return do so by choice (rather than because of being dead) and still manage to have children. Same for their exiles.
Vorcha: that's just how they work. See the codex.
Rachni: While few even know they exist, which likely means Mordin doesn't know anything about their genetics, there are two very obvious reasons: either they're totally extinct, or there's a single queen and all the rest are her children.
We don't know enough about the Batarians or Hanar to say anything one way or the other. Possibly with the Volus, it has something to do with them originating in a very different sort of biosphere than basically every other known species. They're likely far less exposed to stellar and cosmic radiation by virtue of living on worlds with very thick atmospheres, and their suits limit exposure when offworld. Similarly, the Elcor have very thick, tough skin, and depending on when that trait arose, they could have had a lowered mutation rate for a very long time indeed.
As far as the Turians, one possible reason is suggested by the fact that their homeworld has a lot of background radiation as a result of a very weak magnetic field (which is why they have that tough pseudo-exoskeleton): in such an environment, mutations would be much, much more common and thus deleterious mutations would be that much more frequent. Having very efficient genetic repair mechanisms would be rather advantageous, but those mechanisms wouldn't really be able to tell a useful mutation from a harmful one, so a side-effect would be lower genetic diversity.
Even if that's not the case, their skin
definitely evolved to block radiation, and that alone will lower their mutation rate quite a bit. Especially since it's a trait shared by most life on Palaven, which means it evolved a very, very long time ago. And that's "long" as in "before the turian species even existed".
