Mitochondrial DNA variation reveals shared maternal lineages between Kazakh and Turkish fat-tailed sheep breeds.
Article in BMC veterinary research, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundLocal livestock breeds represent a significant genetic resource shaped by historical human migrations. While morphological similarities between Central Asian and Anatolian sheep breeds have long suggested a shared ancestry, molecular evidence linking these populations to specific historical migrations remains limited. This study investigates the genetic diversity and phylogenetic relationships of Kazakh (Edilbay) and Turkish (Akkaraman, Morkaraman, Awassi) fat-tailed sheep breeds using mtDNA D-loop sequencing to explore the maternal lineages of these historically connected populations.
methodsThe study included Edilbay sheep from Atyrau (Kazakhstan) and Akkaraman (Kırşehir), Morkaraman (Iğdır), and Awassi (Şanlıurfa) sheep from Türkiye. Genomic DNA was extracted using the salt precipitation method. A 531 bp fragment of the mtDNA control region (D-loop) was amplified. Genetic diversity indices were calculated using DnaSP v6, while population structure (AMOVA and pairwise F
resultsOur results reveal high levels of genetic diversity (Hd: 0.990) in the studied populations, indicating a rich maternal genetic diversity in the region. We found a very low genetic differentiation (F
conclusionsThese findings clarify the maternal genetic structure of these indigenous breeds and support a historical connection, highlighting the Morkaraman and Edilbay as conserved genetic reservoirs of a shared pastoral heritage.
