A single-gene trait refers to a characteristic or a phenotype that is controlled by one gene. In each gene trait, it can be controlled by two or three phenotypes. ... On the other hand, a polygenic trait is influenced bytwo or more genes, wherein the traits have a wide variety of p...
This suggests that trait exaggeration is associated with gene regulation in a leg-dependent manner. Genes with female-biased expression may therefore have evolved as a consequence of the strong sexual selection on male exaggerated legs, in addition to the antagonistic selection on females to escape ...
If4x<13, what is the possible range of values for x? View Solution If4x<−13, what is the possible range of values for x? View Solution If a polygenic trait is controlled by 3 polygenes, what will beF2phenotypic ratio? View Solution ...
A trait's genomic architecture can affect the rate and mechanism of adaptation, and although many ecologically-important traits are polygenic, most studies connecting genotype, phenotype, and fitness in natural populations have focused on traits with relatively simple genetic bases. To understand the ...
The presence of phenomena analogous to phase transition in Statistical Mechanics has been suggested in the evolution of a polygenic trait under stabilizing selection, mutation and genetic drift. By using numerical simulations of a model system, we analyze the evolution of a population of N diploid ...
For gene–trait pairs that passed the SMR test, we performed the heterogeneity in dependent instruments (HEIDI) test, with PHEIDI≥ 0.05 reflecting that we could not reject a single causal variant with effects on both molecular phenotype and complex trait. As a cis-regulator, lncRNA can ...
Interacting proteins tend to have similar functions, influencing the same organismal traits. Interaction networks can be used to expand the list of candidate trait-associated genes from genome-wide association studies. Here, we performed network-based expansion of trait-associated genes for 1,002 human...
Osteoporosis is a polygenic trait [40], whereby increased bone fragility results from increased adipocytes and osteoclastogenesis and insufficient osteoblastogenesis [41]. When looking at the functions of the different genes present in the Blue module, we find many genes which have a clear function ...
polygenic inheritance. Correlations among polygenic traits occur due to linkage and/or pleiotropic effect114. The better the correlations among traits the more likely it is that breeders can indirectly select one trait based on other traits with high heritability. In the current study, we found a...
have contributed towards a better understanding of the functions of rhythm processing17,24, it is less clear how rhythmic differences arise and how these are maintained over time. Bird song frequency has a tight relationship with body mass25,26, and is likely polygenic27. Temporal features of ...
