A gene's ability to buffer variation is predicted by its fitness contribution and genetic interactions. [PDF]

PLoS ONE, 2011
BACKGROUND: Many single-gene knockouts result in increased phenotypic (e.g., morphological) variability among the mutant's offspring. This has been interpreted as an intrinsic ability of genes to buffer genetic and environmental variation.

Morphological Characterization, Variability and Diversity among Vegetable Soybean (Glycine max L.) Genotypes

Plants, 2021
Vegetable soybean production is dependent on the development of vegetable type varieties that would be achieved by the use of germplasm to evolve new agronomically superior yielding vegetable type with beneficial biochemical traits.

Weak Genetic Isolation and Putative Phenotypic Selection in the Wild Carnation Dianthus virgineus (Caryophyllaceae)

Biology, 2023
By relating genetic divergence at neutral loci, phenotypic variation, and geographic and environmental distances, it is possible to dissect micro-evolutionary scenarios involving natural selection and neutral evolution.

Development of a robust and quantitative high-throughput screening method for assessing phenotypic variation in large Neisseria meningitidis isolate collections

MethodsX, 2023
Genome-wide association studies are a powerful approach for identifying determinants of disease. For infectious diseases, high throughput assays are required for measuring the variance in multiple virulence-related phenotypes of large bacterial isolate ...

Phenotypic variation and developmental instability of life-history traits: a theory and a case study on within-population variation of resting eggs formation in Daphnia

Journal of Limnology, 2004
It is commonly accepted that within-population phenotypic variation is caused by genotypic and environmental heterogeneity. Non-genotypic variation is thought to result from diversity of environmental conditions alone.

Phenotypic variation of a new synthetic allotetraploid Arabidopsis kamchatica enhanced in natural environment

Frontiers in Plant Science, 2023
The phenotypic variation of vegetative organs and reproductive organs of newly synthesized and natural Arabidopsis kamchatica genotypes was investigated in both a controlled environment and a natural environment in an experimental garden.

Geographical variation in neonatal phenotype [PDF]

Acta Obstetricia et Gynecologica Scandinavica, 2006
AbstractBackground. Recent studies have shown associations between size and body proportions at birth and health outcomes throughout the life cycle, but there are few data on how neonatal phenotype varies in different populations around the world. Methods.

Phenotypic Variations in Wolfhirschhorn Syndrome [PDF]

Balkan Journal of Medical Genetics, 2014
Abstract Wolf-Hirschhorn syndrome (WHS) is a rare chromosomal disorder caused by terminal deletion of the short arm of chromosome 4. The clinical picture includes growth retardation, severe mental retardation, characteristic “Greek helmet” like face, seizures and midline defects in the brain, heart, palate and genitalia. Recently-used

Phenotypic diversity in natural populations of an endangered plant Tetracentron sinense

Botan‪ical Sciences, 2017
Background: Tetracentron sinense, distributed mainly in central and southwest China, is a threatened deciduous broad-leaved canopy tree. Presently, little is known about the phenotypic diversity in natural populations of T.

Expansive Phenotypic Landscape of Botrytis cinerea Shows Differential Contribution of Genetic Diversity and Plasticity

Molecular Plant-Microbe Interactions, 2016
The modern evolutionary synthesis suggests that both environmental variation and genetic diversity are critical determinants of pathogen success. However, the relative contribution of these two sources of variation is not routinely measured.
