When you look at Tali’s face through the visor, you can’t help but notice how human –like her facial features are. The possibility is that quarians are actually very close to humans genetically speaking. Like us, Quarians have an endoskeleton, lips, teeth, and two eyes with eyelids and tear ducts. Females also have mammary glands, which is what mammals use to feed their young with. It is believed that quarians evolved from creatures similar to earth’s higher primates, an evolution that naturally is a human equivalent originating on another planet.
The origin of life on any planet probably starts off the same, which is why things like bacteria exist everywhere. The difference being that each evolves in its own way to handle the varying conditions but doesn't entirely change, hence the bacteria. Evolution is simply reading traits in a new way to achieve a better survival/success rate.
We know that all life shares at least a little of their genetic codes. This is why we are more closely related to rats than we would otherwise think. This means that humans are already related, at least partially, to the other alien races that exist in the Mass Effect universe. Our closest relatives on Earth are chimpanzees, but they don’t share our upright postures and other physical advantages. If you notice, most of the sentient life in that universe share a similar body frame, and indication of shared genetics that aren’t even shared by our closest relatives on earth.
The main structure of DNA is the nucleotides. These are the base pairings which give DNA its code. In humans, Adenine binds with Thymine, Cytosine with Guanine, and so on. The more that these codes match, the better the odds of having a hybrid child. We already know based on the things above that quarians likely share a good portion of their DNA with humans. Since the full genetic code for any alien species is unknown, even to the developers themselves, the genetic code could contain further similarities to that of humans.
We already know that hybrids are possible even from situations that have occurred on earth. Ligers, mules, walphins, and a few others have already emerged from the cross-breeding of different animals. Admittedly there are usually many problems associated with this process. Mortality rates among the unborn and sterilization are just a couple of problems facing hybrid children. These potential risks are likely to be a problem with human-quarian children, however, these problems may be able to be corrected, or at least lessened , by Mass Effect’s technology. Different gene therapies, for example, may be use to correct defects and eliminate certain genetics that are dangerous to the new child.
It is likely that there would be genetic skirmishes that occur when the genes meet. For example, humans have levo –based amino acids and quarians have dextro-based amino acids. This is, according to modern science,
a big problem in creating a child. However, there are ways that this can be overcome through future technology's
bio-engineering. It does present a problem, but then any problem can be overcome with the right method.
Junk DNA from both species would likely be dropped. For example, in human genetics the small toe is no longer needed for balance. Such genetics would likely be lost to allow for a better mix which would be a compromise between the genetics. The new child, for example, would likely have four fingers on each hand (including the index finger and thumb) and four toes on each foot.
So maybe a hybrid child is possible, just not probable because of limited interspecies interaction and having a low success rate. There would likely be complications, I’ll admit that, but the possibility still remains. Given what we know, what is yet unknown, and Mass Effect’s future technology they can make it work. All it will take is an explanation from the developers, either ingame or outside. This explanation wouldn’t need to get too detailed, just enough to confirm what I’ve already said. Hopefully we can make this work and I look forward to seeing the different responses to this forum.
Note: I have updated the paragraph on the genetic skirmishes.
