Genotypic‐specific variance in
Ecology and Evolution, 2014 AbstractOrganisms live in heterogeneous environments, so strategies that maximze fitness in such environments will evolve. Variation in traits is important because it is the raw material on which natural selection acts during evolution. Phenotypic variation is usually thought to be due to genetic variation and/or environmentally induced effects ...

Frontiers in Plant Science, 2022 Genomic prediction has been established in breeding programs to predict the genotypic values of selection candidates without phenotypic data. First results in wheat showed that genomic predictions can also prove useful to select among material for which ...

Relative importance of the epistatic components of genotypic variance in non-inbred populations
Crop Breeding and Applied Biotechnology, 2004 There are theoretical approaches about genic interaction in polygenic systems and methodologies to confirm its occurrence. However, some relevant aspects as the relative importance of the epistatic components of genotypic variance deserve further ...

BMC Genetics, 2009 Background Cockerham genetic models are commonly used in quantitative trait loci (QTL) analysis with a special feature of partitioning genotypic variances into various genetic variance components, while the F∞ genetic models are widely used in genetic ...

Refinements to the partitioning of the inbred genotypic variance [PDF]
Heredity, 2003 Natural gene flow is often localised because of gamete dispersal limitations, and the quantity and structure of the genotypic variance in such populations is a key to predicting the advance from selection, in both evolution and artificial breeding programmes. Earlier derivations of this variance have shown that the total dominance variance may increase

Genetic heterogeneity of residual variance in broiler chickens [PDF]
, 2006 Aims were to estimate the extent of genetic heterogeneity in environmental variance. Data comprised 99 535 records of 35-day body weights from broiler chickens reared in a controlled environment.

ESTIMATINON GENOTYPIC PHENOTYPIC VARIANCES FOR BARLEY GENOTYPES [PDF]
Mesopotamia Journal of Agriculture, 2013 Twenty four genotype of barley were used in addition to the local variety (black barley), according to random complete block design (R.C.B.D.) with three replications under the rainfed conditions of northern area of Iraq. The characters were studied.

Role of COVID-19 Genotype in Pathogenesis
International Journal of Endorsing Health Science Research, 2021 Background: Corona viruses are not new to us, and there are 15 different variants known to us. In the last 20 years, this is the fourth coronavirus outbreak, and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) seems to be the deadliest ...

Variance component analysis of skin and weight data for sheep subjected to rapid inbreeding [PDF]
, 1999 A variance component analysis was carried out on data from a 20-year experiment in the rapid inbreeding of purebred and crossbred lines of three hill breeds of sheep.

Multiple mating but not recombination causes quantitative increase in offspring genetic diversity for varying genetic architectures. [PDF]
PLoS ONE, 2012 Explaining the evolution of sex and recombination is particularly intriguing for some species of eusocial insects because they display exceptionally high mating frequencies and genomic recombination rates. Explanations for both phenomena are based on the
