Divergent ancestry of Korean native and Thai chickens with independent gene pool retention by Korean commercial chickens.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveThe objective is to investigate the genetic variation and linkages of Korean native chickens (KNCs), which are regarded as a significant genetic resource due to their distinctive features, however remain inadequately studied in these aspects. In this study, we investigated the genetic variation within five KNC varieties: Korean commercial chicken (KOR-C/M), Silkie (KOR-KS), Leghorn (KOR-LH)-all imported and adapted varieties-and two pureline KNCs: Korean traditional Gray Brown (KOR-KGB) and Korean traditional Yellow Brown (KOR-KYB).
methodsThe relationship of KNCs with chicken breeds from Thailand was evaluated using microsatellite genotyping.
resultsHigh genetic diversity was observed among the KNC breeds, with KOR-KYB showing the highest heterozygosity, whereas KOR-C/M exhibited the lowest heterozygosity and signs of inbreeding. The loci MCW0016, ADL0268, MCW0081, MCW0067, MCW0248, MCW0165, ADL0278, and MCW0330 were identified as being under directional selection. Genetic clustering analyses indicated four distinct clusters, with KOR-C/M differing from other KNC breeds. Distinct gene pools were observed between KNC breeds and indigenous and local chicken populations, as well as red junglefowl in Thailand, suggesting that they have evolved separately. However, connections may exist due to shared ancestry and crossbreeding.
conclusionClustering analysis revealed that KNC breeds formed a separate group from indigenous and local chickens and red junglefowl in Thailand. The distinct genetic patterns suggest independent evolution of the KNC and local Thai breeds, although shared ancestry and crossbreeding may have introduced some connections. These findings bear significant implications for the conservation and sustainable management of KNC populations.
