Classical, Ancestral, and New Inbreeding of X-Chromosome in Czech Local Dairy Goat Breed
, 2023 The importance of the autosomal inbreeding coefficient for livestock production traits is well documented. In contrast, little is known about inbreeding coefficients for X-chromosomes in livestock populations. On the other hand, several studies have shown that genes on the X-chromosome can contribute to variation in the breeding values of traits ...

A Century of Understanding and Harnessing Heterosis
Plant Breeding, EarlyView.ABSTRACT Heterosis has shaped modern plant breeding since Darwin's 19th century observations that outcrossing restores vigour lost through selfing. While 100 years old, its mechanistic basis and deployability remain actively debated. Classical models of dominance, overdominance and epistasis provided the foundation for hybrid breeding and converted ...

The Plant Genome, Volume 19, Issue 4, December 2026.Abstract Crimson clover (Trifolium incarnatum L.) is an obligately outcrossing, cool‐season annual legume valued for forage and cover cropping, yet genomic resources to support systematic improvement are limited. We performed the first whole‐genome re‐sequencing of global crimson clover germplasm to (i) develop a public mid‐density enrichment capture ...

Journal of Dairy ScienceThe objective of this study was to assess the effect of using or not using the genotypes of the parents of a cow for imputing SNPs on the estimation of genomic inbreeding coefficients of cows. Imputation (i.e., genotyped plus imputed) genotypes from 68,127 Italian Holstein dairy cows registered in the Italian National Association of Holstein, Brown ...

The Plant Genome, Volume 19, Issue 4, December 2026.Abstract One strategy for increasing the genetic diversity of upland cotton (Gossypium hirsutum) involves the introgression of beneficial alleles from related and wild tetraploid species. Progress in this area has been limited due to undesirable outcomes associated with whole genome interspecific hybridization. To minimize genetic influences from other

The Weight of Genetic Drift: A Pedigree-Based Evaluation of the Breton Horse Population in Brazil
Veterinary Medicine InternationalThe genetic diversity of Breton horses in Brazil is a critical concern, mainly due to the small population size and low number of births per year. Given that the inbreeding was overlooked by breeders for multiple generations, we estimated the genetic ...

Agriculture and Biology Journal of North America, 2011 The objectives of the present study were to investigate the effect of the inbreeding and the rate of genetic plasma from Arabian breed regarding the body proportions in real Shagya population. The analyses of variance of the indexes for bone system development, compactness, massiveness and chest development and estimations of the levels of factors were

The Plant Genome, Volume 19, Issue 4, December 2026.Abstract Genome‐wide association studies (GWASs) typically require large populations to achieve sufficient statistical power; however, maintaining large populations is labor‐intensive and costly. In this study, we evaluated the feasibility of improving GWAS detection power by strategically integrating small maize (Zea mays L.) subpopulations for kernel‐
