Phenotypic Divergence along Lines of Genetic Variance [PDF]
The American Naturalist, 2005 Natural populations inhabiting the same environment often independently evolve the same phenotype. Is this replicated evolution a result of genetic constraints imposed by patterns of genetic covariation? We looked for associations between directions of morphological divergence and the orientation of the genetic variance-covariance matrix (G) by using ...

Estimated Heterogeneity of Phenotypic Variance of Test-Day Yield with a Structural Variance Model [PDF]
Journal of Dairy Science, 2004 First-lactation test-day milk, fat, and protein yields from New York, Wisconsin, and California herds from 1990 through 2000 were adjusted additively for age and lactation stage. A random regression model with third-order Legendre polynomials for permanent environmental and genetic effects was used.

An equilibrium for phenotypic variance in fluctuating environments owing to epigenetics [PDF]
Journal of The Royal Society Interface, 2011 Abstract The connection between random environments and genetic and phenotypic variability has been a major focus in the population genetic literature. By providing differential access to the underlying genetic information, epigenetic variation could play an important role in the interaction between environmental and phenotypic ...

Phenotypic variance in pediatric obstructive sleep apnea
Pediatric Pulmonology, 2021 AbstractIt is crucial that clinicians understand what underpins the considerable phenotypic variance in pediatric obstructive sleep apnea syndrome (OSAS), if they are to implement individually tailored phenotype‐based approaches to diagnosis and management.

Des différences, pourquoi? Transmission, maintenance and effects of phenotypic variance. [PDF]
J Anim Ecol, 2016 1. Despite the observed distribution of variable individual phenotypes, survival and reproductive performance in wild populations, models of population dynamics often focus on mean demographic rates.

The Distribution of Phenotypic Variance with Inbreeding [PDF]
Evolution, 1999 Fifty-two inbred populations of Drosophila melanogaster, each founded from a single pair, and a large number of control, outbred flies were measured for fitness and a set of six traits. A survey of the literature on the effects of inbreeding and population bottlenecks demonstrates that the commonly observed pattern of an apparent variance among ...

GENETIC PARAMETERS OF SOME SORGHUM (SORGHUM BICOLOR (L.) MOENCH) GENOTYPES UNDER WATER DEFICIT STRESS [PDF]
Egyptian Journal of Desert Research, 2020 Sorghum (Sorghum bicolor(L.) Moench) has a mighty adaptation possibility, which are important parameters of genotypes growing in severe conditions. This study focused on the differential responses of six genotypes under two levels of water deficit (20 ...
