Haplotypic polymorphisms and forensic applications in Chinese Hunan Han population based on a series of Y-STR loci: a perspective of paternal inheritance

Annals of Human Biology, 2023
Background Hunan, a multinational province in China, possesses more than fifty ethnic groups, such as the Han, Yao, Tujia, Miao, and so on. Aims To evaluate the forensic efficiency of the novel panel and investigate the genetic relationships between ...

Growth, competition and cooperation in spatial population genetics [PDF]

, 2012
We study an individual based model describing competition in space between two different alleles. Although the model is similar in spirit to classic models of spatial population genetics such as the stepping stone model, here however space is continuous ...

Structural and Temporal Variation in Genetic Diversity of European Spring Two-Row Barley Cultivars and Association Mapping of Quantitative Traits

The Plant Genome, 2013
Two hundred sixteen barley ( L.) cultivars were selected to represent the diversity and history of European spring two-row barley breeding and to search for alleles controlling agronomic traits by association genetics.

Technologically modified genes in natural populations [PDF]

, 1993
Current theories of evolutionary and ecological genetics cannot be used for general statements on risk assessment of gene technology. In a simplifying model, the genes which are transferred from artificial populations are treated like mutations in the ...

Hitchhiking to speciation. [PDF]

PLoS Biology, 2013
The modern evolutionary synthesis codified the idea that species exist as distinct entities because intrinsic reproductive barriers prevent them from merging together. Understanding the origin of species therefore requires understanding the evolution and

The dynamics of alternative pathways to compensatory substitution [PDF]

, 2013
The role of epistatic interactions among loci is a central question in evolutionary biology and is increasingly relevant in the genomic age. While the population genetics of compensatory substitution have received considerable attention, most studies ...

Genotype by random environmental interactions gives an advantage to non-favored minor alleles

Scientific Reports, 2017
Fixation probability, the probability that the frequency of a newly arising mutation in a population will eventually reach unity, is a fundamental quantity in evolutionary genetics.

Simulating population genetics of pathogen vectors in changing landscapes: guidelines and application with Triatoma brasiliensis. [PDF]

PLoS Neglected Tropical Diseases, 2014
BACKGROUND:Understanding the mechanisms that influence the population dynamics and spatial genetic structure of the vectors of pathogens infecting humans is a central issue in tropical epidemiology.

The look-ahead effect of phenotypic mutations [PDF]

, 2007
The evolution of complex molecular traits such as disulphide bridges often requires multiple mutations. The intermediate steps in such evolutionary trajectories are likely to be selectively neutral or deleterious.

Hybrid fitness effects modify fixation probabilities of introgressed alleles

G3: Genes, Genomes, Genetics, 2022
Hybridization is a common occurrence in natural populations, and introgression is a major source of genetic variation. Despite the evolutionary importance of adaptive introgression, classical population genetics theory does not take into account hybrid ...
