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 ...

Waves of range dynamics and gene flow characterize the biogeographic history of Litsea elongata, a dominant tree in East Asian evergreen broadleaved forests

PLANTS, PEOPLE, PLANET, EarlyView.
Evergreen broadleaved forests (EBLFs) represent an iconic vegetation type in subtropical montane East Asia, but they are experiencing intensifying anthropogenic pressure and increasing habitat fragmentation. Here, using a dominant and widespread tree species characteristic of East Asian EBLFs, we examine its phylogeographic history and evaluate what it

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,

From wild to tamed: Reimagining novel crops through omics and local plant diversity

PLANTS, PEOPLE, PLANET, EarlyView.
The global food system faces growing pressure from climate change, biodiversity loss, and rising nutritional demands. Agriculture has increased yields but reduced crop diversity, flavor, and nutritional quality, leaving societies vulnerable and dependent on a narrow set of staple species.

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 ...

Genomic patterns of homozygosity and inbreeding depression in Murciano-Granadina goats

Journal of Animal Science and Biotechnology, 2022
Abstract Background Inbreeding depression can adversely affect traits related to fitness, reproduction and productive performance. Although current research suggests that inbreeding levels are generally low in most goat breeds, the impact of inbreeding depression on phenotypes of economic interest has only been ...

Genomic architecture and breeding trade‐offs of coconut drought tolerance

PLANTS, PEOPLE, PLANET, EarlyView.
The coconut palm is an extremely popular and economically important crop, with around 65 million tonnes produced in 2023. Although Africa's coconut sector is growing rapidly, it—and the livelihoods that depend on it—is threatened by climate change, particularly increased drought.

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 ...

Balancing gain and diversity: Optimal contribution selection for sustainable genetic improvement in sugarcane. [PDF]

Plant Genome
Abstract Sugarcane (Saccharum spp. hybrids), the source of ∼80% of the worlds sugar, has experienced a plateau in genetic improvement over recent decades. This stagnation is largely due to the crop's complex polyploid genome and long breeding cycles, which limit the efficiency of traditional selection methods.
