Human‐Mediated Dispersal Routes Structure Sahara Mustard Genomics

open access: yesMolecular Ecology, Volume 34, Issue 24, December 2025.
ABSTRACT Humans have facilitated the spread and evolution of invasive species, a pattern that has accelerated with the globalisation of trade and societal development. Consequently, the invasiveness of a species may be determined not only by how many propagules and which genotypes are introduced, but also by its evolutionary history and how humans have

On the Consequences of Purging and Linkage on Fitness and Genetic Diversity

open access: yesG3: Genes, Genomes, Genetics, 2016
Using computer simulation we explore the consequences of linkage on the inbreeding load of an equilibrium population, and on the efficiency of purging and the loss of genetic diversity after a reduction in population size.

Host-parasite coevolutionary dynamics with generalized success/failure infection genetics [PDF]

open access: yes, 2015
Host-parasite infection genetics can be more complex than envisioned by classic models such as the gene-for-gene or matching-allele models. By means of a mathematical model, I investigate the coevolutionary dynamics arising from a large set of ...

Designing superior crosses in cassava using genomic mating to boost yield and genetic diversity

open access: yesCrop Science, Volume 65, Issue 6, November/December 2025.
Abstract Identifying superior cassava (Manihot esculenta Crantz) crosses through phenotypic evaluations is costly and inefficient due to cassava's long breeding cycles and low flowering rates. In this study, we applied genomic mate selection and optimum contribution selection using additive, dominance, and directional dominance models to enhance ...

Detection of QTLs for Yield Heterosis in Rice Using a RIL Population and Its Testcross Population

open access: yesInternational Journal of Genomics, 2016
Analysis of the genetic basis of yield heterosis in rice was conducted by quantitative trait locus mapping using a set of 204 recombinant inbred lines (RILs), its testcross population, and mid-parent heterosis dataset (HMP).

Overdominance in the Human Genome and Olfactory Receptor Activity

open access: yesMolecular Biology and Evolution, 2008
We investigate the contribution of overdominance to the maintenance of polymorphism in the human genome during the recent evolution of our species. Using the HapMap genotypic information, we have detected that the Gene Ontology term "olfactory receptor activity" is a molecular function overrepresented in genes that have SNPs (Single Nucleotide ...

Overdominance Effects between Malaria and Visceral Leishmaniasis in the 5q31 Region

open access: yes, 2015
A group of SNPs in 5q31, genotyped from Hausa tribe of Koka village in eastern Sudan; an area endemic with malaria and visceral leishmaniasis, were analyzed by The Leishmaniasis research group and found to have significant excess of heterozygosis level ...

A new approach to investigate arthropod biodiversity in forest ecosystems, using meta‐barcoding on trap combinations

open access: yesEcological Solutions and Evidence, Volume 6, Issue 4, October–December 2025.
For biodiversity monitoring of arthropods with a limited additional fieldwork, our trap combination reduced the taxonomic bias in the local samples compared to other studies relying only on Malaise traps. This represented the orders of the local fauna better.

Behavioural overdominance of honeybee colonies kept simultaneously on standard-cell and small-cell combs

open access: yesAnimal
Overdominance is often observed in the case of intergenic interactions and is referred to as one of the major factors determining hybrid vigour or heterosis.

Identification of the single base change causing the callipyge muscle hypertrophy phenotype, the only known example of polar overdominance in mammals.

open access: yesGenome Research, 2002
A small genetic region near the telomere of ovine chromosome 18 was previously shown to carry the mutation causing the callipyge muscle hypertrophy phenotype in sheep.
