Increasing power for voxel-wise genome-wide association studies : the random field theory, least square kernel machines and fast permutation procedures [PDF]

open access: yes, 2012
Imaging traits are thought to have more direct links to genetic variation than diagnostic measures based on cognitive or clinical assessments and provide a powerful substrate to examine the influence of genetics on human brains. Although imaging genetics

Performance characteristics of the boson rapid SARS–cov–2 antigen test card vs RT–PCR: Cross–reactivity and emerging variants

open access: yesHeliyon, 2023
Background: SARS–CoV–2 virus has undergone several mutations on its genome, since the onset of the pandemic. Multiple variants of concern (VOC) have emerged including Alpha, Beta, Gamma, and Delta with the more recent one being the Omicron (B.1.1.529 ...

The SSR Null Allele Problem, and Its Consequences in Pedigree Reconstruction and Population Genetic Studies in Viticulture

open access: yesHorticulturae, 2022
Null alleles are alleles that are recessive to codominant markers without any effect on the phenotype. In SSR assays, there are several reasons for the lack of amplification at a locus: the primer does not bind well, longer fragments do not amplify due ...

lociNGS: a lightweight alternative for assessing suitability of next-generation loci for evolutionary analysis. [PDF]

open access: yesPLoS ONE, 2012
Genomic enrichment methods and next-generation sequencing produce uneven coverage for the portions of the genome (the loci) they target; this information is essential for ascertaining the suitability of each locus for further analysis.

Comparative genome analysis identifies few traits unique to the Escherichia coli ST131 H30Rx clade and extensive mosaicism at the capsule locus [PDF]

open access: yes, 2014
Background: E.coli ST131 is a globally disseminated clone of multi-drug resistant E. coli responsible for that vast majority of global extra-intestinal E. coli infections.

GENETIC CHANGE IN MUTATIONS AT THE T/t-LOCUS IN THE MOUSE [PDF]

open access: yesGenetics, 1976
ABSTRACT Recessive lethal or semilethal alleles at the T/t locus in the mouse generate new t-variants, with characteristics different from the parent allele at a rate of about 10-3. Almost invariably the variant chromosome carries marker genes derived from the opposite parental chromosome.

Neurospora mating type symbol mt revised to mat [PDF]

open access: yes, 1997
After discussion with members of the Neurospora genetics community, we propose to revise the symbol designating the mating type locus from mt to ...

Mutation analysis of 21 autosomal short tandem repeats in Han population from Hunan, China

open access: yesAnnals of Human Biology, 2019
Background: Short tandem repeats (STRs) are powerful genetic markers widely used in human genetics. Population data and locus-specific mutation rates of STRs are crucial for the evaluation and interpretation of genetic evidence in forensic and population
