Reticulate evolution and beneficial organismspart I

Sympatric populations of white-tailed deer and mule deer . . . share a common mitochondrial DNA restriction map genotype.

The distribution of chloroplast genotypes in this group indicates that sympatric species of oak in the eastern United States do not represent fully isolated gene pools, but are actively exchanging genes.

A preponderance of interspecific allelic interactions involved one locus each in the two different subgenomes of (allotetraploid) Gossypium, thus supporting several other lines of evidence suggesting that intersubgenomic interactions contribute to unique features that distinguish tetraploid cotton from its diploid ancestors.

This finding confirms that inter-specific hybridization between wolves and dogs can occur in natural wolf populations.

. . . swamp buffaloes have an unraveled mitochondrial history, which can be explained by introgression of wild buffalo mtDNA into domestic stocks.

Grapevine was selected because of its important place in the cultural heritage of humanity beginning during the Neolithic period . . . This analysis reveals the contribution of three ancestral genomes to the grapevine haploid content.
