A general population genetic theory for the evolution of developmental interactions.
نویسنده
چکیده
The development of most phenotypic traits involves complex interactions between many underlying factors, both genetic and environmental. To study the evolution of such processes, a set of mathematical relationships is derived that describe how selection acts to change the distribution of genetic variation given arbitrarily complex developmental interactions and any distribution of genetic and environmental variation. The result is illustrated by using it to derive models for the evolution of dominance and for the evolutionary consequences of asymmetry in the distribution of genetic variation.

The geometry of phenotypic evolution in developmental hyperspace.
C traits are constructed during development by an intricate array of factors, and interactions among factors, including DNA, RNA, proteins, developmental modules, and various aspects of the biotic and abiotic environment. As a result, it is development that structures the relationship between the genotype and phenotype and thereby determines genetic architecture. The genotype–phenotype relation...
متن کاملUnveiling the genetic loci for a panicle developmental trait using genome-wide association study in rice
Panicle size has a high correlation with grain yield in rice. There is a bottleneck to identify the additional quantitative trait loci (QTL) for panicle size due to the conventional traits used for QTL mapping. To identify more genetic loci for panicle size, a panicle developmental trait (LNTB, the length from panicle neck-knot to the first primary branch in the rachis) related to panicle size ...
متن کاملA new metaheuristic genetic-based placement algorithm for 2D strip packing
Given a container of fixed width, infinite height and a set of rectangular block, the 2D-strip packing problem consists of orthogonally placing all the rectangles such that the height is minimized. The position is subject to confinement of no overlapping of blocks. The problem is a complex NP-hard combinatorial optimization, thus a heuristic based on genetic algorithm is proposed to solve it. I...
متن کاملA MODEL FOR EVOLUTIONARY DYNAMICS OF WORDS IN A LANGUAGE
Human language, over its evolutionary history, has emerged as one of the fundamental defining characteristic of the modern man. However, this milestone evolutionary process through natural selection has not left any ’linguistic fossils’ that may enable us to trace back the actual course of development of language and its establishment in human societies. Lacking analytical tools to fathom the cr...
متن کاملMINI REVIEW A gene’s eye view of epistasis, selection and speciation
The genetic architecture of a phenotype consists of the genes, the interactions among them (epistasis), and the interactions among genes and environments (G · E) that affect the phenotype’s expression (Wade et al., 2001). For a phenotype with a ‘complex’ genetic architecture, epistasis and G · E play significant roles as opposed to a phenotype with a ‘simple’ architecture, in which interactions...
