What would the average skin tone and facial features look like after 300 years if every partner relationship was interracial until there were no other ethnicities? Just a hodgepodge of DNA. What would the average human look like having a little bit of everything in them?
I just think the idea is neat is all.
That’s not really how genetics works
Correct me if I am wrong, but as I understand it the dominant traits will always win over the recessive traits. For two dominant alleles that do not have complete dominance, the trait can be shared.
However, for things like skin pigments it isn’t so black and white (ha) there are a variety of genes that determine it. The question then becomes what are the truly dominate set of traits that would win statistically in the genetic fight if they were all mixed?
