It's not possible to get a "full elf" by breeding half-elves with pure elves and continuing to introduce pure elven blood over generations...no matter how hard you may try. Best you can get is a half-elf.
I thought that a half-elf and a half-elf could make full-elf babies... One-fourth of the time.
This would imply that there is one recessive elf chromosome. I would have to imagine that a half elf has more then 1 elf chromosome....AeonBlues
Elves are an inherently mystical race. By tainting their blood even a little with the human genome which, while hardy, is pretty much the epitome of mundane you effectively impare, to some degree, the offspring's mystical nature. It won't matter whether its 1% or 75%. Physical traits may vary and show as more or less elven but the physical and mystical traits are a world apart and not mutually exclusive.The name Half Elf is a very general classification and not really a racial designation so while your character may be offended at being called a half elf when he's two thirds or three quarters.. it has no bearing on the label.
