Differential introgression and the maintenance of species boundaries in an advanced generation avian hybrid zone [PDF]

open access: yes, 2016
Background: Evolutionary processes, including selection and differential fitness, shape the introgression of genetic material across a hybrid zone, resulting in the exchange of some genes but not others.

An alternative experimental case–control design for genetic association studies on bovine mastitis

open access: yesAnimal, 2017
The possibility of using genetic control strategies to increase disease resistance to infectious diseases relies on the identification of markers to include in the breeding plans.

Marker-free transgenic plants through genetically programmed auto-excision [PDF]

open access: yes, 2007
We present here a vector system to obtain homozygous marker-free transgenic plants without the need of extra handling and within the same time frame as compared to transformation methods in which the marker is not removed.

Allele frequency for c.335 A>C polymorphisms in porcine ghrelin/obestatin prepropeptide gene and association analysis with performance traits in various pig breeds

open access: yesCzech Journal of Animal Science, 2015
The allelic frequency of c.335A>C polymorphisms in the porcine ghrelin/obestatin prepropeptide (GHRL) gene was surveyed among six pig breeds and two subspecies of wild boars. The c.335C was the most frequent allele in Berkshire, Landrace, Large White,

Levels of genetic polymorphism: marker loci versus quantitative traits [PDF]

open access: yes, 1998
Species are the units used to measure ecological diversity and alleles are the units of genetic diversity. Genetic variation within and among species has been documented most extensively using allozyme electrophoresis.

A polymorphism in the stearoyl-CoA desaturase gene promoter influences monounsaturated fatty acid content of Duroc × Iberian hams

open access: yesSpanish Journal of Agricultural Research, 2015
Data on 74 dry-cured hams from Duroc × Iberian pigs were used to examine whether the tag polymorphism AY487830:g.2228T>C in the promoter region of the stearoyl-CoA desaturase [SCD] gene affect fat desaturation and monounsaturated fatty acid (MUFA) as ...

Evaluating Metabarcoding Markers for Identifying Zooplankton and Ichthyoplankton Communities to Species in the Salish Sea: Morphological Comparisons and Rare, Threatened or Invasive Species

open access: yesDNA, 2023
Zooplankton and ichthyoplankton community assessments depend on species diagnostics, yet morphological identifications are time-consuming, require taxonomic expertise, and are hampered by a lack of diagnostic characters, particularly for larval stages ...

Controlling the Overfitting of Heritability in Genomic Selection through Cross Validation. [PDF]

open access: yes, 2017
In genomic selection (GS), all the markers across the entire genome are used to conduct marker-assisted selection such that each quantitative trait locus of complex trait is in linkage disequilibrium with at least one marker.

Genome scan of Diabrotica virgifera virgifera for genetic variation associated with crop rotation tolerance [PDF]

open access: yes, 2007
Crop rotation has been a valuable technique for control of Diabrotica virgifera virgifera for almost a century. However, during the last two decades, crop rotation has ceased to be effective in an expanding area of the US corn belt.

Genome-Wide Analysis of Genetic Diversity in Plasmodium falciparum Isolates From China–Myanmar Border

open access: yesFrontiers in Genetics, 2019
Plasmodium falciparum isolates from China–Myanmar border (CMB) have experienced regional special selective pressures and adaptive evolution. However, the genomes of P. falciparum isolates from this region to date are poorly characterized.
