Effects of Epistasis and Pleiotropy on Fitness Landscapes
The factors that influence genetic architecture shape the structure of the fitness landscape, and therefore play a large role in the evolutionary dynamics. Here the NK model is used to investigate how epistasis and pleiotropy -- key components of genetic

Mixed Outcomes in Recombination Rates After Domestication: Revisiting Theory and Data
ABSTRACT The process of domestication has altered many phenotypes. Selection on these phenotypes has long been hypothesised to indirectly select for increases in the genome‐wide recombination rate. This hypothesis is potentially consistent with theory on the evolution of the recombination rate, but empirical support has been unclear. We review relevant

An “immortalized F2” (IF2) population and two reciprocal backcross (HSBCF1 and MARBCF1) populations were constructed to investigate the genetic bases of fiber quality traits in upland cotton across four different environments.

Coexistence in Sympatry With Gene Flow Before Speciation Has Completed
ABSTRACT Incipient species often coexist in sympatry before complete reproductive isolation has evolved between them. How do they persist in the face of hybridization and gene flow? The challenge is more acute than ordinary ecological coexistence not only because gene flow erodes and recombines genetic differences, but also because selection against ...

Complexity of evolutionary equilibria in static fitness landscapes [PDF]
A fitness landscape is a genetic space -- with two genotypes adjacent if they differ in a single locus -- and a fitness function. Evolutionary dynamics produce a flow on this landscape from lower fitness to higher; reaching equilibrium only if a local ...

Quantitative analyses of empirical fitness landscapes
The concept of a fitness landscape is a powerful metaphor that offers insight into various aspects of evolutionary processes and guidance for the study of evolution.

Genetics of Common Obesity in Children and Adolescents
Abstract Childhood obesity is a multifactorial public health problem worldwide. Genetic variation influences the predisposition to develop obesity at early stages of life. Childhood obesity may be classified as syndromic, monogenic, or polygenic depending on the genetic component.

ABSTRACT Cucumis melo, a sweet‐tasting fruit from the Cucurbitaceae family, is popular in global markets. While some varieties of C. melo are used for pickling or salads, melons such as cantaloupes and honeydews are consumed as a dessert. Desirable appearance, shelf life and palatability are crucial in determining a variety's success.

Epistasis facilitates functional evolution in an ancient transcription factor
A protein’s genetic architecture – the set of causal rules by which its sequence produces its functions – also determines its possible evolutionary trajectories.

From Classical Genetics to Quantitative Genetics to Systems Biology: Modeling Epistasis
Gene expression data has been used in lieu of phenotype in both classical and quantitative genetic settings. These two disciplines have separate approaches to measuring and interpreting epistasis, which is the interaction between alleles at different loci. We propose a framework for estimating and interpreting epistasis from a classical experiment that
