yea but codex say a quarians are most human like species
Superficially human.
Learn you some science son:
http://en.wikipedia....i/Fertilisationhttp://en.wikipedia....ybrid_(biology)Basically, the only hybrid animals we have exist within, at most, a Family of species. There has never been a recorded hybrid organism at the level of the Order.
To put things in perspective, you can create a mule by breeding a horse and a donkey because they're in the same Family. But you can't breed a Horse and a Tapir, even though they're in the same Order, because there's already too much genetic disimilarity there. Even more, you can't breed a Horse and a Bengal Tiger, even though their in the same class: Mammals. And you can't breed a horse and an Octopus, even though they're both Animals. And you can't breed a horse and an Elm Tree, even though they share an extremely distant common ancestor.
Now, consider this: A tree is more genetically similar to a human being that a Quarian is, since the Quarian shares 0 common ancestry with the Human.
So the short answer is: no, it is absolutely impossible.
Here are some specific reasons:
1. Gamete recognition: i.e., quarian egg might not accept human sperm and vice versa. They might never interact at all.
Assume you had gametic compatability, which would be absurd, but lets assume it happened:
2. Chromosome mismatch: I would assume that they we do not have similar numberd of chromosomes and genes as quarians, the odds would be astronomoical. But even if we did, the fact that our DNA is mismatched means that when the chromosomes lined up, it's literally impossible for them to then contain a complete list of instructions for building an organism.
Assume that somehow the chromosomes did match up, and assuming that somehow the different chirality of DNA didn't much things up, and assuming that somehow two organisms which don't share any common ancestry at all are able to produce via hybrid offspring, then...
3. Fetal Development: as a zygote becomes a blastocyst becomes an embryo becomes a fetus, it's constantly interacting with it's mother via the placenta and the umbilical chord. Now you have to deal with how incompatable the hybrid offspring's biology would be with the human or quarian mother's biology. The mother's immune system might attack the fetus as a hostile, alien entity, since it is. The fetus might be poisoned by the nutrients the mother takes in, or even by the mother's blood and stuff.
The list goes on and on and on.
Of course, I suppose it might be possible with space magic.
