Abstract

Abstract The introduction of Iberian cattle in the Americas after Columbus’ arrival imposed high selection pressures on a limited number of animals over a brief period of time. Knowledge of the genomic regions selected during this process may help in enhancing climatic resilience and sustainable animal production. We first determined taurine and indicine contributions to the genomic structure of modern Creole cattle. Second, we inferred their demographic history using approximate Bayesian computation (ABC), linkage disequilibrium (LD) and Ne Slope (NeS) analysis. Third, we performed whole genome scans for selection signatures based on cross‐population extended haplotype homozygosity (XP‐EHH) and population differentiation (FST) to disentangle the genetic mechanisms involved in adaptation and phenotypic change by a rapid and major environmental transition. To tackle these questions, we combined SNP array data (~54,000 SNPs) in Creole breeds with their modern putative Iberian ancestors. Reconstruction of the population history of Creoles from the end of the 15th century indicated a major demographic expansion until the introduction of zebu and commercial breeds into the Americas ~180 years ago, coinciding with a drastic Ne contraction. NeS analysis provided insights into short‐term complexity in population change and depicted a decrease/expansion episode at the end of the ABC‐inferred expansion, as well as several additional fluctuations in Ne with the attainment of the current small Ne only towards the end of the 20th century. Selection signatures for tropical adaptation pinpointed the thermoregulatory slick hair coat region, identifying a new candidate gene (GDNF), as well as novel candidate regions involved in immune function, behavioural processes, iron metabolism and adaptation to new feeding conditions. The outcomes from this study will help in future‐proofing farm animal genetic resources (FAnGR) by providing molecular tools that allow selection for improved cattle performance, resilience and welfare under climate change.

  • DDX23, a heat shock gene, showed up-regulation in Sahiwal peripheral blood mononuclear cells from tropical regions relative to Ladakhi cattle from hypobaric hypoxia regions.

    “DDX23, a heat shock gene, showed up-regulation in Sahiwal peripheral blood mononuclear cells from tropical regions relative to Ladakhi cattle from hypobaric hypoxia regions [108,109].”

    From The Genomic Landscape of Cattle: Domestication, Dispersal, and Adaptive Evolution (2026) · cites this paper as [109]

    The Results and Discussion section reports genomic selection signals related to heat tolerance in Creole cattle, not gene-expression measurements in Sahiwal or Ladakhi blood cells. Searches for DDX23, peripheral blood mononuclear cells, and hypobaric hypoxia found no passage addressing the claimed comparison. Page numbers were unavailable in our copy. (LLM, conf=0.75)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
