pleiotropy

Razeto-Barry P, Díaz J, Cotras D & Vásquez RA 2011 Molecular evolution, mutation size and gene pleiotropy: a geometric reexamination. Genetics 187:877-885. Gu (2007a,b) used a bottom–up approach for the generation of mutational random vect…

near neutrality

Gu X 2007 Stabilizing selection of protein function and distribution of selection coefficient among sites. Genetica 130:93-97. the evolutionary conservation of protein function can be viewed as a set of several (K) molecular phenotypes tha…

near neutrality

Gu X 2007 Evolutionary framework for protein sequence evolution and gene pleiotropy. Genetics 175:1813–1822. the evolutionary fate of a mutant is largely determined by the prespecified fitness value (the coefficient of selection) and the e…

near neutrality

Hartl DL & Taubes CH 1998 Towards a theory of evolutionary adaptation. Genetica 102/103:525-533. nothing is known about the distribution of selective effects of newly arising mutations the statement that 'most mutations are harmful' is of …

near neutrality

Hartl DL & Taubes CH 1996 Compensatory nearly neutral mutations: selection without adaptation. J Theor Biol 182:303-309. a significant fraction of nucleotide substitutions should be slightly detrimental most genes undergo selectively drive…

pleiotropy

Martin G & Lenormand T 2006 A general multivariate extension of Fisher's geometrical model and the distribution of mutation fitness effects across species. Evolution 60:893-907. there may be a cost to phenotypic complexity although much we…

pleiotropy

Welch JJ & Waxman D 2003 Modularity and the cost of complexity. Evolution 57:1723-1734. we examine the claim that the rate of evolution of complex phenotypes could be accelerated through some sort of phenotypic modularity we consider the p…

pleiotropy

Orr HA 2000 Adaptation and the cost of complexity. Evolution 54:13-20. fitness is determined by n independent (orthogonal) characters at each of our n characters, fitness falls off as a Gaussian function of distance, zi, from the optimum F…

compensatory evolution

fisherian geometry

Peck JR, Barreau G & Heath SC 1997 Imperfect genes, Fisherian mutation and the evolution of sex. Genetics 145:1171-1199. mutant effects are biased there is a correlation between the state of an allele before mutation, and its postmutation …

compensatory evolution

Hastings A 1987 Substitution under stabilizing selection. Genetics 116:479-486. one of the most interesting and important questions facing population genetics today is the relationship between selection at the level of the organism and sel…
