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.

The African Mole‐Rat Genus Cryptomys and Its Species: Distinct in Their Genes and Habitats

Zoologica Scripta, EarlyView.
ABSTRACTThe African mole‐rat genus Cryptomys comprises five morphologically cryptic lineages distributed across South Africa and in Zimbabwe, historically treated as subspecies of C. hottentotus (C. h. hottentotus, C. h. mahali, C. h. natalensis, C. h. pretoriae and C. h. nimrodi).

Management of inbreeding and coancestry to target short-term and long-term genetic gains

, 2022
Inbreeding is not heritable. This means that breeding for low inbreeding generally has a transient and non-accumulating impact over generations. This is a bit like selecting for a trait that has a heritability of zero.

Seascape Genomics Uncovers Weak Signs of Local Adaptation Despite Bottleneck Events, High Inbreeding and Low Heterozygosity in the Vulnerable Smooth Hammerhead Shark (Sphyrna zygaena)

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 9, September 2026.
ABSTRACT The smooth hammerhead shark (Sphyrna zygaena) is a highly migratory pelagic predator classified as Vulnerable due to overexploitation and rapid climate change. However, its genomic diversity, connectivity patterns and demographic history remain poorly understood.

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.

Panmixia in a Widespread Butterfly: High Dispersal and Ecological Generalism Buffer Against Landscape Fragmentation

Ecology and Evolution, Volume 16, Issue 9, September 2026.
The study examined the genetic structure of Pieris rapae across western Germany and found no genetic differentiation or isolation by distance. Fragmented agricultural landscapes did not reduce genetic connectivity compared to more heterogeneous systems, indicating near‐panmixia across the region.

Mean and variance of coancestry and inbreeding coefficients calculated using genealogical, microsatellite or SNP data.

, 2013
Notice that inbreeding coefficients provide equivalent information than self-coancestries. Results were obtained when using the subset of 30 Guadyerbas animals genotyped for both microsatellite and SNP markers.aAverage coancestry coefficient including ...

Fast and accurate joint inference of coancestry parameters for populations and/or individuals.

PLoS Genetics, 2023
We introduce a fast, new algorithm for inferring from allele count data the FST parameters describing genetic distances among a set of populations and/or unrelated diploid individuals, and a tree with branch lengths corresponding to FST values.
