Genomic analysis reveals convergent signatures of selection for milk traits in sheep and goats.
Article in Journal of animal science and biotechnology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
backgroundConvergent evolution offers a unique lens through which to explore the molecular underpinnings of significant phenotypic transformations. Similar selective pressures likely drove the evolution of analogous milk traits in sheep and goats. Consequently, the current study aimed to identify common selection signals for milk traits across dairy and non-dairy breeds of sheep and goats worldwide.
resultsIn this study, a total of 308 whole-genome sequences from diverse sheep (n = 108) and goat (n = 200) breeds, including both dairy and non-dairy types, across the world were utilized. The population structure and genetic diversity of dairy and non-dairy sheep and goat breeds were characterized. Species-specific genes associated with milk traits, such as POU2F1, ABCD2, TRNAC-GCA in sheep and PRPF6, VPS13C, TPD52L2, NFX1 and B4GALT1 in goats, were identified. Further gene annotation and bioinformatics analyses indicated that different biological pathways are important for milk traits in each species: fatty acid oxidation and AMP metabolic process in sheep, the U2-type spliceosomal complex and propanoate metabolism in goats. Additionally, common signatures of selection such as CLASP1, PDS5B, ZNF831, CCDC73 were found in sheep and goats. Haplotype and transcriptional analyses further confirmed the role of these genes in milk production and provided evidence for their analogous evolution in sheep and goats. The CLASP1 gene was identified as a target of convergent selection, representing a promising candidate for genetic improvement programs in dairy species.
conclusionsThese results provide insights into the genetic basis of convergent dairy traits, offering valuable targets for improving milk production and advancing dairy sheep and goat breeding programs.
