Additive Variance and Open‐Pollinated Progenies Under Mixed Mating

Plant Breeding, EarlyView.
ABSTRACT Open‐pollinated progeny tests are still widely interpreted as if all the individuals within a maternal family were true half‐sibs. However, in species with mixed mating systems, this assumption is often biologically unrealistic and may bias the estimation of the additive variance, narrow‐sense heritability and expected selection gains.

Use of Cluster Analysis for Identifying Metafounders

Journal of Animal Breeding and Genetics, Volume 143, Issue 4, Page 535-559, July 2026.
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

Unravelling Past Population Events in Diatoms With Genomic Based Demographic Inferences

Marine Ecology, Volume 47, Issue 4, July/August 2026.
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.

Revisiting Genetic Relationships of the Endangered Austrian Turopolje With Balkan and Commercial Pig Breeds Using Genome‐Wide SNP Data

Animal Genetics, Volume 57, Issue 3, June 2026.
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 ...

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.

3RAD‐Guided SNP Discovery for Species Identification and Conservation of the Medicinal Southern African Tree Genus Greyia Hook. & Harv.

Ecology and Evolution, Volume 16, Issue 5, May 2026.
A two‐phase SNP discovery and assay‐development strategy was used to resolve species boundaries within the tree genus Greyia, as overlapping phenotypes and distributions limit accurate identification. From 47,726 genome‐wide SNPs generated by 3RAD sequencing, a diagnostic 23‐SNP Type panel was developed and validated, successfully distinguishing G ...

Assessing Genetic Diversity and Inbreeding Effects in an Endangered Amphibian: Effects of Ecological Restoration and Stochasticity

Ecology and Evolution, Volume 16, Issue 5, May 2026.
This study evaluated the genetic health of the endangered Rawlinsonia littlejohni following habitat modification and climatic variability. We identified two genetically distinct sub‐populations separated by limited gene flow, with heterozygosity remaining higher and inbreeding lower in the northern sub‐population containing both natural and constructed

Improving Pedigree-based Linkage Analysis by Estimating Coancestry Among Families [PDF]

Statistical Applications in Genetics and Molecular Biology, 2012
We present a method for improving the power of linkage analysis by detecting chromosome segments shared identical by descent (IBD) by individuals not known to be related. Existing Markov chain Monte Carlo methods sample descent patterns on pedigrees conditional on observed marker data.
