Problem:
The diploid chromosomal architecture is rather interesting. For example, because of diploidy we Humans have to mate. Of course in that sense, because diploid organisms often have mate, this has led to emergence of sexual organs as novel features etc.
But, what I am interested in, is the prospect of recombination and mating being able to lead to drastically novel evolutionary traits.
For example, if a remote tribesman from the Pygmy peoples of Central Africa were to mate with an urban dweller, one theoretical example of a novel feature could emerge in the offspring are new inter-gene/protein interactions between these "never met before" sets of alleles. Recombination would then "seal the deal" by shuffling these allele sets between the maternal/paternal chromosomes, such an individual's offspring would now become a mosaic of their hybrid parent. Just imagine cross-over events occurring between two very divergent promoters of the same loci.
Required:
Question: Could the unison of such divergent sets of alleles theoretically lead to unique phenotype and features that bear little resemblance to any features belonging to the parents?
Quetion: Are there any real examples of morphological/physiological features such as that I have tried to describe?
Any help would be greatly appreciated!
