Inbreeding and coancestry trends in Nordic Holstein
Increased rates of inbreeding have been observed in several Holstein populations across the world since genomic selection (GS) was implemented into the breeding programs. The objective of this study was to test whether this is also the case in the Nordic Holstein population using pedigree data.

Management of genetic diversity in small farm animal populations*
Many local breeds of farm animals have small populations and, consequently, are highly endangered. The correct genetic management of such populations is crucial for their survival.

ABSTRACT Conservation assessments of imperiled species require information on population structure, abundance, and connectivity which benefit from integrated demographic and genetic data. Humboldt martens (Martes caurina humboldtensis) are a federally threatened subspecies of Pacific marten (Martes caurina) whose conservation has been hindered by ...

Detecting linkage between a trait and a marker in a random mating population without pedigree record. [PDF]
Modern linkage-based approaches employing extended pedigrees are becoming powerful tools for localizing complex quantitative trait loci. For these linkage mapping methods, it is necessary to reconstruct extended pedigrees which include living individuals,

Use of Cluster Analysis for Identifying Metafounders
ABSTRACT In the metafounder approach, the relationship matrix of metafounders, Γ is used to transfer information on relationships between pedigree founders into the numerator relationship matrix A, creating matrix AΓ. Commonly metafounders are defined based on the available information of the animal (e.g., country, sex, breed) similar to unknown parent

Effect of non-random mating on genomic and BLUP selection schemes
Background The risk of long-term unequal contribution of mating pairs to the gene pool is that deleterious recessive genes can be expressed. Such consequences could be alleviated by appropriately designing and optimizing breeding schemes i.e.

Unravelling Past Population Events in Diatoms With Genomic Based Demographic Inferences
ABSTRACT The biological productivity in the Southern Ocean is mainly driven by the abundance of phytoplankton, which changes with seasons, fluctuations in sea ice and iron as well as light availability. The distribution of biological productivity is further modulated by ocean currents.

ABSTRACT The endangered Austrian Turopolje (AT) pig population, which originated from six Croatian Turopolje founders imported during the early 1990s, is nowadays preserved through a national conservation project. This study aims to identify genetic relations, genetic distances and migration events between the AT population, four Austrian commercial ...
