Genomic inbreeding coefficients using imputed genotypes: Assessing different estimators in Holstein-Friesian dairy cows

Journal of Dairy Science, 2022
: The objective of this study was to estimate inbreeding coefficients in Holstein dairy cattle using imputed SNPs data. A data set of 95,540 Italian Holstein dairy cows from the routine genomic evaluations of the Italian National Association of Holstein,

Evolution and Phylogenetics of the Javan Hawk‐Eagle Nisaetus bartelsi (Stresemann, 1924) Using Mitochondrial Data 爪哇鹰雕 Nisaetus bartelsi (Stresemann, 1924) 基于线粒体数据的演化与系统发育研究

Integrative Conservation, EarlyView.
This study reconstructs the phylogeny of the Javan Hawk‐Eagle (Nisaetus bartelsi) within the subfamily Aquilinae using Maximum Likelihood and Bayesian Inference algorithms on a blood sample and GenBank data. The analysis reveals that the sampled genus Nisaetus forms a monophyletic group. Furthermore, N. bartelsi occupies a sister‐taxon of N.

Comparing Genomic and Pedigree Inbreeding Coefficients in the Slovenian Lipizzan Horse as a Case Study for Small Closed Populations

Animals
In small, closed populations such as the Lipizzan horse, maintaining genetic diversity while limiting inbreeding is a key challenge in conservation breeding.

Effect of recent and ancient inbreeding on production and fertility traits in Canadian Holsteins

BMC Genomics, 2020
Background Phenotypic performances of livestock animals decline with increasing levels of inbreeding, however, the noticeable decline known as inbreeding depression, may not be due only to the total level of inbreeding, but rather could be distinctly ...

Leaf micromorphology and genetic diversity analysis of Iranian Hordeum species using ISSR and SCoT markers

Nordic Journal of Botany, EarlyView.
The genus Hordeum (Poaceae), of the tribe Triticeae, comprises approximately 32 species with substantial potential for barley improvement. Hordeum vulgare is an economically important cereal widely cultivated across diverse environments, from the Arctic to desert and humid regions.

Optimizing genetic diversity in Australian Holsteins and Jerseys: A comparative analysis of whole-genome and regional inbreeding depression effects

Journal of Dairy Science
: Homozygosity, which can arise from several genetic mechanisms including inbreeding, is frequently observed in the offspring of related parents. This inbreeding can lead to a reduced performance, owing to a phenomenon known as inbreeding depression ...

Estimate of inbreeding depression on growth and reproductive traits in a Large White pig population

G3: Genes, Genomes, Genetics, 2022
With the broad application of genomic information, SNP-based measures of estimating inbreeding have been widely used in animal breeding, especially based on runs of homozygosity.

Range‐wide sampling reveals cryptic lineages but largely conserved mycorrhizal associations in the Japanese fairy lantern Thismia kobensis

PLANTS, PEOPLE, PLANET, EarlyView.
The jewel‐like flowers of Thismia are as rare as they are beautiful, often recorded from only a single site per species. Access to 15 populations of T. kobensis has enabled an uncommon, range‐wide assessment of morphology, genetics, and fungal partners. Our analyses showed that T.

Inbreeding affects the survival of Danish Jersey and Holstein dairy cows

Journal of Dairy Science
: This study evaluated the effects of pedigree and genomic inbreeding on survival in Danish Jersey (JER) and Danish Holstein (HOL) dairy cows. Survival probabilities and hazard risks (HR) were estimated using Kaplan–Meier analysis and Cox proportional ...

Inbreeding depression due to recent and ancient inbreeding in Dutch Holstein–Friesian dairy cattle

Genetics Selection Evolution, 2019
Background Inbreeding decreases animal performance (inbreeding depression), but not all inbreeding is expected to be equally harmful. Recent inbreeding is expected to be more harmful than ancient inbreeding, because selection decreases the frequency of ...
