A fractal pattern of hierarchical genetic population structure in mixed stocks across fish segregated by dams revealed by genomic resources for curimba Prochilodus lineatus

open access: yesJournal of Fish Biology, EarlyView.
Abstract Genomic resources, new microsatellite markers and a novel observation of a fractal pattern in the genetic population structure are presented for curimba, Prochilodus lineatus, a freshwater migratory model species of South America. Our main goals were to investigate the presence of mixed fish stocks and the effects of damming‐induced ...

Stem microanatomical phenomic uncovers a potential role for ZmLSM2 in regulating maize stem bending strength

open access: yesJournal of Integrative Plant Biology, EarlyView.
Maize ZmLSM2 (U6 small nuclear ribonucleoprotein specific Sm‐like 2) controls maize stem strength by affecting vascular bundle structure. Using advanced computed tomography imaging and artificial intelligence identified key stem traits linked to lodging resistance and developed a predictive model.

A Principled Framework for Mendelian Randomization in Oral Health Research

open access: yesJournal of Periodontal Research, EarlyView.
This methodological article provides a clear and accessible overview of Mendelian randomization for oral health researchers, emphasizing the core assumptions needed for credible causal inference. Focusing on applications in oral health, particularly periodontitis, it highlights both the strengths and limitations of the study design in order to support ...

Genetic Susceptibility to Periodontitis

open access: yesJournal of Periodontal Research, EarlyView.
Aim: The aim of this narrative review was to identify genes carrying risk alleles associated with an increased risk of periodontitis and to place them in a biological context. Methods: The literature was reviewed based on predefined criteria. Results: The identified genes largely fall into functions linking immune response with tissue repair. The genes

Inferences about Linkage Disequilibrium

Biometrics, 1979
Existing theory for inferences about linkage disequilibrium is restricted to a measure defined on gametic frequencies. Unless gametic frequencies are directly observable, they are inferred from genotypic frequencies under the assumption of random union of gametes.

Third order linkage disequilibrium*

Tissue Antigens, 1984
For third order linkage disequilibrium there is a constraint on the maximum value the disequilibrium can take, given pairwise disequilibria values and allele frequencies. As distinct from second order disequilibrium (considered in the context of a two locus model) there is also in some cases a constraint on the minimum value. The appropriate procedures

[Linkage disequilibrium].

Journal de genetique humaine, 1981
The linkage disequilibrium which measures the association between linked genes is a temporary phenomenon in a population because of crossing over. But such associations persist in HLA system. These persistent linkage disequilibria may be due to the very small fraction of recombinaison between the loci but other explanations are possible: selection or ...
