Mating schemes for optimum contribution selection with constrained rates of inbreeding

Genetics Selection Evolution, 2000
The effect of non-random mating on genetic response was compared for populations with discrete generations. Mating followed a selection step where the average coancestry of selected animals was constrained, while genetic response was maximised.

Democracy, Judicial Attitudes and Heterogeneity: The Civil Versus Common Law Tradition [PDF]

, 2009
A key issue in the design of a legal system is the choice of the mechanism aggregating citizens ’ preferences over the harshness of punishment. While under Case law appellate judges ’ biases offset one another at the cost of volatility of the law, under ...

Genomic Connectivity and Adaptation Signals of the Freshwater Sponge Ephydatia muelleri Across Its Distribution

Journal of Biogeography, Volume 53, Issue 1, January 2026.
ABSTRACT Aim Genetic connectivity and local adaptation were examined across the distribution of the freshwater sponge Ephydatia muelleri. Because it occupies an exceptional breadth of freshwater environments across a broad geographic range, this species offers key insights into biogeographic processes shaping genetic structure and adaptation in inland ...

Pedigree Analysis of Modern Muscadine Cultivars Reveals a Narrow Genetic Base

Journal of the American Society for Horticultural Science, 2023
Muscadine grape (Vitis rotundifolia var. rotundifolia) is a rare crop in that it has transitioned from a wild fruiting plant to a domesticated fruit within the past 150 years.

Global population divergence and admixture of the brown rat (Rattus norvegicus) [PDF]

, 2016
Native to China and Mongolia, the brown rat (Rattus norvegicus) now enjoys a worldwide distribution. While black rats and the house mouse tracked the regional development of human agricultural settlements, brown rats did not appear in Europe until the ...

Estimation of coancestry in Iberian pigs using molecular markers

Conservation Genetics, 2002
Genetic markers provide a useful tool to estimate pairwise coancestry between individuals in the absence of a known pedigree. In the present work 62 pigs from two related strains of Iberian breed, Guadyerbas and Torbiscal, belonging to a conservation programme with completely known pedigrees since 1945, have been genotyped for 49 microsatellites.

Advantages of using molecular coancestry in the removal of introgressed genetic material [PDF]

Genetics Selection Evolution, 2013
When introgression of undesired exogenous genetic material occurs in a population intended to remain pure, actions are necessary to recover the original background. It has been shown that genome-wide information can replace pedigree information for different objectives and is a valuable tool in the fields of genetic conservation and breeding.

Extensive photophysiological variation in wild barley is linked to environmental origin

New Phytologist, Volume 249, Issue 1, Page 569-587, January 2026.
Summary Intraspecific variation between crop wild relatives (CWRs) represents a source of untapped genetic diversity for crop improvement. At the same time, improving photosynthesis in crops has the potential to enhance yield. Thus, exploring variation for photophysiology within CWRs is an important, yet underexplored, research area.

Genomic Inbreeding and Relatedness in Wild Panda Populations. [PDF]

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.
