Could the world eventually become one race through the interbreeding of races over time?

Genetically speaking is it possible? I would like to know more about how dom/recess genes work with skin complexion as i’m just basing this question on the layman’s observation that interracial couples produce mixed childen whose skin complexion lies somewhere between the two.. This would also be assuming an idealistic future world society millions of years down the road whose moralities have progressed past all prejudice/racism/tribalism due to globalization/integration/social reform.

Yes, and no.

In a perfect scenario where everyone interbred equally you could achieve this.

However, in practice, even just two communities who live in different environments and do not interbreed equally will eventually grow to have different genetic developments that are specific to their situation.

This will become a much larger problem once we colonize space. The reality is that, without FTL, *Humanity* might be sending out the colonization ships, but it sure won’t be Humanity who will colonize those stellar bodies when they arrive. Throw a few ten thousand years over it and those people will have evolved in way different ways.
