God-is-a-Taco: Isn't this true for most distinctly "white" traits? I don't think it'll happen by 2100, but as more and more interacial stuff goes on we'll all look quite plain I would think.

Nope, genes are particulate, they don't "blend" (that's a pre-Mendelian notion of genetics that is still quite widely believed in the general public). Even if every single redhead alive today reproduced only with dark-haired sub-Saharan Africans, the red hair genes would persist. They probably would not be expressed in the first generation offspring, but all of the offspring would be heterozygous (carrying but not expressing the "broken" MC1R allele and well as the natural variant that is expressed). The red hair (light skin, freckles, blue/green eyes, etc.) would be masked for a generation or more, but eventually, the descendants of today's redheads will mate and some of their offspring will inherit the MC1R variant ("red hair gene") from both parents and display the traits.

There will still be red hair as long as there are descendants of redheads. It might not always be associated with light colored skin (although the MC1R variant does have an influence on skin color as well) but the gene itself will persist.

Have no fear of humanity becoming one homogenized mass; we won't all "meet in the middle" so to speak. Genes just don't work that way. Your kids might get your hair color and your wife's eye color, for example, but they won't get a blend of eye colors or hair colors; it's one or the other.

As a (flawed but useful) analogy, consider two strings of beads, one all red and one all blue. The red strand represents your genes and the blue represents your wife's genes. Your kids will get a combination, a mix of some red beads and some blue beads, but they won't get any purple ones.

It's much more complicated than that of course, and I'd be happy to go on at length, but I don't want to bore you. Hope that helped.

One of the best threads ever! But...I'm surprised that a few Farkers posted pics of their ex-girlfriends. What, do you keep those pix around for just such a thread?
