Parental relatedness through time revealed by runs of homozygosity in ancient DNA
Nature Communications, 2021 Parental relatedness of present-day humans varies substantially across the globe, but little is known about the past. Here we analyze ancient DNA, leveraging that parental relatedness leaves genomic traces in the form of runs of homozygosity.

Runs of homozygosity in killer whale genomes provide a global record of demographic histories
Molecular Ecology, 2021 Runs of homozygosity (ROH) occur when offspring inherit haplotypes that are identical by descent from each parent. Length distributions of ROH are informative about population history; specifically, the probability of inbreeding mediated by mating system

Identification of runs of homozygosity associated with male fertility in Italian Brown Swiss cattle
Frontiers in Genetics, 2023 Intensive selection for improved productivity has been accompanied by an increase in inbreeding rates and a reduction in genetic diversity. The increase in inbreeding tends to impact performance, especially fitness-related traits such as male fertility ...

Homozygosity and Linkage Disequilibrium [PDF]
Genetics, 2002 AbstractWe illustrate how homozygosity of haplotypes can be used to measure the level of disequilibrium between two or more markers. An excess of either homozygosity or heterozygosity signals a departure from the gametic phase equilibrium: We describe the specific form of dependence that is associated with high (low) homozygosity and derive various ...

Association of IL-4 Polymorphisms with Allergic Rhinitis in Jordanian Population
Medicina, 2020 Background and objectives: Allergic rhinitis has complex patterns of inheritance, and single nucleotide polymorphisms, a common genetic variation in a population, exert a significant role in allergic rhinitis pathology.

Genetics of Inherited Retinal Diseases in Understudied Populations
Frontiers in Genetics, 2022 Retinitis pigmentosa is one of the major forms of inherited retinal dystrophy transmitted in all Mendelian and non-Mendelian forms of inheritance. It involves the loss of retinal photoreceptor cells with severe loss of vision or blindness within the ...

The prospects for using haploinducers in maize breeding
Биотехнология и селекция растений, 2020 The discovery of spontaneous haploid plants and the development of ways to produce them in in vitro culture have set a new direction important for breeding and for theoretical research in reproductive biology.
