The role of recombination on genome-wide patterns of local ancestry exemplified by supplemented brook charr populations
The local ancestry profiles of stocked brook charr populations make it possible to examine domestic introgression at several scales of the genome. The authors show the value of ancestry tracts for studying the dynamics of admixture and its interactions with recombination.
- The question
- How does domestic ancestry vary over time and along chromosomes after stocking?
- The approach
- Analysis of mapped SNP markers in 611 individuals from 24 populations, with estimation of ancestry tracts and recombination.
- What the article brings
- The distribution of ancestry tracts reveals evolutionary processes that vary between genomic regions.
- The limits
- The evolutionary mechanisms proposed remain interpretations, distinct from a causal demonstration. The full text consulted is the preprint, earlier than the published article.
