Skin
The skin of Quarians is shielded from UV rays both by restriction to ships and their suits; this means that they will have no melanin in their skin. Melanin is the reason for colour in humans, and it is almost independent
of genes. It is the melanin concentration of the parents which determines the child’s skin colour, which is why an interracial couple will generate a “Hybrid child”. Quarians, having no need for melanin, will no longer have skin colours of a darker shade than a very pale white.
This may have already been commented on, but I don't have the patience to read all 10 pages of this thread to find out, so I apologize if this is a repetitive post.
I don't believe this statement on skin is true. The Quarians have only been exiled to ships for 300 years, which is not nearly enough time for evolution to change any of the Quarian's features. Changes like this take thousands of years, but if the Quarians did stay on ships for several thousand years, than yes, their melanin would eventually be close to non existent.
If your statement were true, then all black people living in Europe today should be white in 300 years, because they no longer need as much UV protection in Europe where people evolved with white skin, than they do in Africa where people evolved with much darker skin. That's not going to happen in just 300 years.
