Molecular characterization and genetic structure of the Nero Siciliano pig breed

Genetics and Molecular Biology, 2010
Nero Siciliano is an autochthonous pig breed that is reared mainly in semi-extensive systems in northeastern Sicily. Despite its economic importance and well-appreciated meat products, this breed is currently endangered.

Genomic Inbreeding and Relatedness in Wild Panda Populations.

PLoS ONE, 2016
Inbreeding and relatedness in wild panda populations are important parameters for panda conservation. Habitat loss and fragmentation are expected to increase inbreeding but the actual inbreeding levels in natural panda habitats were unknown.

Sensitivity of inferences in forensic genetics to assumptions about founding genes

, 2009
Many forensic genetics problems can be handled using structured systems of discrete variables, for which Bayesian networks offer an appealing practical modeling framework, and allow inferences to be computed by probability propagation methods.

Inbreeding and coancestry in natural populations of Anadenanthera colubrina var. cebil [PDF]

, 2014
La endocría y la coancestría aumentan la homocigosis generando genotipos autocigotas sin afectar a las frecuencias alélicas. Puede considerarse que una muestra de loci selectivamente neutros permite hacer inferencias acerca del coeficiente de endocría de

Genomic analysis of inbreeding and coancestry in Nordic Jersey and Holstein dairy cattle populations

Journal of Dairy Science
In recent years, genomic selection (GS) has accelerated genetic gain in dairy cattle breeds worldwide. Despite the evident genetic progress, several dairy populations have also encountered challenges such as heightened inbreeding rates and reduced effective population sizes. The challenge has been to find a balance between achieving substantial genetic

Genetic diversity loss due to selection for scrapie resistance in the rare Spanish Xalda sheep breed [PDF]

, 2013
Lipid contained in embryonic cells can adversely affect survival of frozen/thawed in vitro produced (IVP) bovine embryos (Leibo et al, Theriogenology 43:265, 1995). Moreover, glycogen accumulates in excess in cells from IVP mouse embryos (Ozias and Stern,

Relationship between genealogical and microsatellite information characterizing losses of genetic variability: Empirical evidence from the rare Xalda sheep breed [PDF]

, 2013
Preservation of rare genetic stocks requires continual monitoring of populations to avoid losses of genetic variability. Genetic variability can be described using genealogical and molecular parameters characterizing variation in allelic frequencies over

Estimation of effective number of breeders from molecular coancestry of single cohort sample

Evolutionary Applications, 2008
AbstractThe effective population size, Ne, is an important parameter in population genetics and conservation biology. It is, however, difficult to directly estimate Ne from demographic data in many wild species. Alternatively, the use of genetic data has received much attention in recent years.
