Multiple Eurasian Origins and Admixture Shaped the Genomic Legacy of the House Mouse Invasion in Africa

Molecular Ecology, Volume 35, Issue 16, August 2026.
ABSTRACT Commensal mammals offer unique opportunities to study how human‐mediated dispersal, admixture, and secondary contact shape genomic variation during range expansion, yet for one of the most successful invasive commensals globally, the western house mouse Mus musculus domesticus, invasion dynamics across Africa remain largely unexplored.

Homozygosity Accumulated Through Genetic Drift and Inbreeding Underpins High Mutation Load in an Endangered Beluga Whale Population

Molecular Ecology, Volume 35, Issue 16, August 2026.
ABSTRACT Isolated populations are susceptible to decline through the accumulation of deleterious mutations and inbreeding depression. As a consequence of habitat alteration, isolated populations are also expected to become increasingly prevalent.

Recent Consanguinity and Outbred Autozygosity Are Associated With Increased Risk of Late-Onset Alzheimer's Disease [PDF]

, 2020
Prior work in late-onset Alzheimer's disease (LOAD) has resulted in discrepant findings as to whether recent consanguinity and outbred autozygosity are associated with LOAD risk.

Large‐Scale Genomics Reveals Three‐Source Ancestry and Layered Adaptation to High Altitude in Tibetan Chickens

Advanced Science, Volume 13, Issue 42, 28 July 2026.
Whole‐genome analysis of 1,054 chickens reveals three ancestral sources (NWC, SYA, and SHF) with distinct temporal entry patterns into the Tibetan Plateau. Route‐specific selection scans, calibrated against a demographic null, suggest complementary functional enrichments—vascular homeostasis (NWC), calcium signaling and cardiac adaptation (SYA), and ...

Imputation in the Wild: Genome‐Wide Robustness and Fine‐Scale Limitations of Low‐Coverage Genomes in Endangered Species

Molecular Ecology Resources, Volume 26, Issue 5, July 2026.
ABSTRACT Low‐coverage whole‐genome sequencing (lcWGS) combined with genotype imputation is increasingly being used to generate large genomic datasets at reduced cost, offering a promising alternative for conservation genomics. Here, we use the Iberian lynx (Lynx pardinus), a species with extremely low genetic diversity, genetically differentiated ...

Genomic dissection of inbreeding depression: a gate to new opportunities

Revista Brasileira de Zootecnia
Inbreeding depression, reduction in performance of quantitative traits, including reproduction and survival, caused by inbreeding, is a well-known phenomenon observed in almost all experimental, domesticated, and natural populations.

Conservation Status of Two Italian Local Poultry Breeds: Faraona Camosciata and Oca Padovana

Animal Genetics, Volume 57, Issue 3, June 2026.
ABSTRACT The present study aimed to assess the conservation status and characterize the phenotypic and genomic diversity of two endangered Italian poultry genetic resources to guide their conservation plans. Blood samples and morphometric data were collected on 50 Faraona Camosciata (FAC, Numida meleagris) and 50 Oca Padovana (OPD, Anser anser) adult ...

AUDACITY: A comprehensive approach for the detection and classification of Runs of Homozygosity in medical and population genomics

Computational and Structural Biotechnology Journal, 2020
Runs of Homozygosity (RoHs) are popular among geneticists as the footprint of demographic processes, evolutionary forces and inbreeding in shaping our genome, and are known to confer risk of Mendelian and complex diseases.
