The paper shows that local ancestry in hybrid swordtail fish populations is repeatable due to strong early selection, and this repeatability increases with deeper evolutionary divergence.

This paper develops wavelet-based methods to analyze local ancestry variation in hybrid populations and finds that selection against introgressed alleles affects up to 20% of genomic variation.

This study shows that selection can repeatedly create similar ecotypes despite low gene flow between parapatric populations of Senecio lautus.
