Pedigree-Based Assessment of Inbreeding Effects on Conformation and Performance Traits in the Peruvian Paso Horse: Implications for Sustainable Genetic Improvement

Austral Journal of Veterinary Sciences
The Peruvian Paso Horse (PPH) is a breed distinguished by its unique four-beat lateral gait. Nowadays, it faces significant genetic challenges related to declining genetic diversity and inbreeding depression, which may substantially affect conformation ...

Pedigree analysis of the Turkish Arab horse population: structure, inbreeding and genetic variability

Animal, 2017
The aim of this study was to evaluate genetic variability in the Turkish Arab horse population using pedigree information. This study is the first detailed pedigree analysis of the breed in Turkey. Pedigree data were collected from the National Studbook.

The MexMAGIC population reveals the genetic architecture of traits exhibiting clinal variation in Mexican native maize

New Phytologist, Volume 252, Issue 3, Page 1296-1313, November 2026.
The MexMAGIC population mixes native maize varieties from across Mexico to study functional genetic diversity. Summary Defining the genetic basis of local adaptation is a key goal of evolutionary biology and crop improvement. Theory predicts that when selective pressures follow differences in the environment, a cline will be established.

Computing inbreeding coefficients accounting for unknown parents using pedigree-based metafounders

JDS Communications
Missing pedigrees result in underestimated numerator relationship and inbreeding coefficients in a closed population. Recursive algorithms have been proposed to derive nonzero inbreeding coefficients accounting for unknown parents but can be ...

Evaluation of Multi‐Breed Genomic Prediction Models for Carcass and Reproductive Traits in Zebu Beef Cattle

Animal Genetics, Volume 57, Issue 5, October 2026.
ABSTRACT Genomic prediction in beef cattle is particularly challenging in breeds with limited phenotypic and genotypic data. In this context, multi‐breed methodologies that integrate information from genetically related populations have emerged as a promising strategy to improve prediction accuracy and calibration under data‐scarce conditions.

Longitudinal study of inbreeding effect on growth traits of Marwari lambs [PDF]

Archives Animal Breeding
This study aimed to assess the impact of inbreeding on growth traits and genetic diversity in a closed flock of Marwari sheep. Data from 11 126 lambs born between 1981 and 2020 at ICAR-CSWRI-ARC in Bikaner, Rajasthan (India), were used to analyse trends ...

SINE Insertion in LAMA3 in Dogs With Junctional Epidermolysis Bullosa

Animal Genetics, Volume 57, Issue 5, October 2026.
ABSTRACT Junctional epidermolysis bullosa (JEB) is a hereditary skin disorder caused by defects in proteins responsible for dermal‐epidermal adhesion. We investigated the genetic cause of JEB in three related mixed‐breed puppies presenting with congenital skin blistering and ulceration. Whole‐genome sequencing of one affected dog followed by comparison

Implementation of Metafounders in the Genomic Prediction for the Polled Trait in Brahman Cattle Using a Multi‐Breed Population

Animal Genetics, Volume 57, Issue 5, October 2026.
ABSTRACT The absence of horns (polled trait) in cattle is associated with better animal welfare by reducing the need for dehorning. In Brahman cattle, population size and the scarcity of phenotypic records challenge the accuracy of genomic predictions for this trait.
