Effect of subdivision of the Lacaune dairy sheep breed on the accuracy of genomic prediction

Journal of Dairy Science, 2023
: Genomic selection was deployed in Lacaune dairy breed in 2015. Lacaune population split in 1972 into 2 breeding companies with associated flocks, and there have been very few exchanges of animals between the subpopulations, leading to divergence of the

Exploring the genetic features and signatures of selection in South China indigenous pigs

Journal of Integrative Agriculture, 2021
To explore the genetic features and signatures of selection in indigenous pigs from South China and Duroc pigs, 259 pigs from six populations were genotyped using single-nucleotide polymorphism (SNP) BeadChips.

Population structure of graptolite assemblages [PDF]

, 1998
Graptolite rhabdosomes display a diverse suite of morphologies. The range of morphotypes present within most moderate to high diversity assemblages from the Ordovician and Silurian is similar, despite the different taxonomic composition of the faunas at ...

Population Connectivity Predicts Vulnerability to White-Nose Syndrome in the Chilean Myotis (Myotis chiloensis) - A Genomics Approach

G3: Genes, Genomes, Genetics, 2020
Despite its peculiar distribution, the biology of the southernmost bat species in the world, the Chilean myotis (Myotis chiloensis), has garnered little attention so far. The species has a north-south distribution of c.
