Rank-invariant estimation of inbreeding coefficients. [PDF]

open access: yes, 2022
The two alleles an individual carries at a locus are identical by descent (ibd) if they have descended from a single ancestral allele in a reference population, and the probability of such identity is the inbreeding coefficient of the individual ...

Beyond Skin and Eyes: The Medical and Social Burden of Oculocutaneous Albinism in Africa: A Narrative Review

open access: yesJEADV Clinical Practice, EarlyView.
ABSTRACT Oculocutaneous albinism (OCA) is a genetic disorder found worldwide, but its impact is particularly pronounced in the African continent. This results from both a higher prevalence and the persistent myths and superstitions surrounding the condition in many African communities.

SITUATION OF INBREEDING IN A RETINTO POPULATION [PDF]

open access: yes, 1996
SUMMARYThe degree of inbreeding was studied for a subpopulation of the beef cattle breed Retintofrom the Cadiz Province in Andalusia (Spain). The pedigree information from 492 female and 25 male breeding animals was analyzed.

Leaf micromorphology and genetic diversity analysis of Iranian Hordeum species using ISSR and SCoT markers

open access: yesNordic Journal of Botany, EarlyView.
The genus Hordeum (Poaceae), of the tribe Triticeae, comprises approximately 32 species with substantial potential for barley improvement. Hordeum vulgare is an economically important cereal widely cultivated across diverse environments, from the Arctic to desert and humid regions.

Range‐wide sampling reveals cryptic lineages but largely conserved mycorrhizal associations in the Japanese fairy lantern Thismia kobensis

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
The jewel‐like flowers of Thismia are as rare as they are beautiful, often recorded from only a single site per species. Access to 15 populations of T. kobensis has enabled an uncommon, range‐wide assessment of morphology, genetics, and fungal partners. Our analyses showed that T.

Slow Recovery from Inbreeding Depression Generated by the Complex Genetic Architecture of Segregating Deleterious Mutations [PDF]

open access: yes, 2022
The deleterious effects of inbreeding have been of extreme importance to evolutionary biology, but it has been difficult to characterize the complex interactions between genetic constraints and selection that lead to fitness loss and recovery after ...

Unraveling Admixture, Inbreeding, and Recent Selection Signatures in West African Indigenous Cattle Populations in Benin

open access: yesFrontiers in Genetics, 2021
The Dwarf Lagune and the Savannah Somba cattle in Benin are typical representatives of the endangered West African indigenous Shorthorn taurine. The Lagune was previously exported to African and European countries and bred as Dahomey cattle, whereas the ...

Waves of range dynamics and gene flow characterize the biogeographic history of Litsea elongata, a dominant tree in East Asian evergreen broadleaved forests

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Evergreen broadleaved forests (EBLFs) represent an iconic vegetation type in subtropical montane East Asia, but they are experiencing intensifying anthropogenic pressure and increasing habitat fragmentation. Here, using a dominant and widespread tree species characteristic of East Asian EBLFs, we examine its phylogeographic history and evaluate what it
