A genomic tale of inbreeding in western Mediterranean human populations

Human Genetics
Abstract Consanguineous marriages are common in many worldwide human populations, and the biological consequences for offspring can be relevant at the biomedical level. The current genomic revolution displayed through genome-wide studies is challenging the paradigm in the analysis of consanguinity.

High level of inbreeding in final phase of 1000 Genomes Project [PDF]

Scientific Reports, 2015
AbstractThe 1000 Genomes Project provides a unique source of whole genome sequencing data for studies of human population genetics and human diseases. The last release of this project includes more than 2,500 sequenced individuals from 26 populations. Although relationships among individuals have been investigated in some of the populations, inbreeding

Impact of inbreeding on production, fertility, and health traits in German Holstein dairy cattle utilizing various inbreeding estimators

Journal of Dairy Science
: In dairy cattle production, it is important to understand how inbreeding affects production, fertility, and health traits. However, there is still limited use of genomic information to estimate inbreeding, despite advancements in genotyping ...

Level of Inbreeding in Norik of Muran Horse: Pedigree vs. Genomic Data

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2019
The objective of this study was to analyse the level of pedigree and genomic inbreeding in a herd of the Norik of Muran horses. The pedigree file included 1374 animals (603 stallions and 771 mares), while the reference population consisted of animals ...

Decades of Enclosure Protection Exert Composite Effects on Grassland Grasshopper Communities

Integrative Zoology, EarlyView.
Decades of enclosure protection have altered grasshopper community structure, with species‐specific effects on population dynamics. For the low‐mobility grasshopper Chorthippus fallax, abundance did not differ strongly between exclosure‐protected and overgrazed areas, but its egg development duration was longer in exclosures. The two C.

Nest Survival Models and Genomics Illuminate Hybridisation Attempts, Guiding Culturally Informed Management to Recover a Critically Endangered Seabird

Animal Conservation, EarlyView.
Long‐term monitoring has revealed hybridisation attempts between the Critically Endangered Kuaka Whenua Hou (KWH, Pelecanoides whenuahouensis) and the abundant Kuaka (P. urinatrix). Here we use modelling based on population monitoring data in tandem with genomic data to investigate these attempts and the risk they pose to KWH recovery.

An inbreeding perspective on the effectiveness of wildlife population defragmentation measures – a case study on wild boar (Sus scrofa) of Veluwe, The Netherlands

Frontiers in Ecology and Evolution
Pervasive inbreeding is a major genetic threat of population fragmentation and can undermine the efficacy of population connectivity measures. Nevertheless, few studies have evaluated whether wildlife crossings can alleviate the frequency and length of ...

Inbreeding and runs of homozygosity before and after genomic selection in North American Holstein cattle

BMC Genomics, 2018
Background While autozygosity as a consequence of selection is well understood, there is limited information on the ability of different methods to measure true inbreeding.

Genotyping Contemporary Captive and Historical Wild Western Lowland Gorillas Indicates Captive Breeding Is Maintaining Genetic Diversity in a Critically Endangered Primate

Animal Conservation, EarlyView.
Captive populations of threatened species risk losing genetic diversity over time. We evaluated the genetic status of contemporary captive western lowland gorillas (Gorilla gorilla gorilla) at Howletts and Port Lympne and compared this with specimens from a historical wild population.
