A new genetic algorithm based on primal-dual chromosomes for royal road functions [PDF]

open access: yes, 2001
Copyright @ 2001 University of LeicesterGenetic algorithms (GAs) have been broadly studied by a huge amount of researchers and there are many variations developed based on Holland’s simple genetic algorithm (SGA). Inspired by the idea of diploid genotype

RGFGA: An efficient representation and crossover for grouping genetic algorithms [PDF]

open access: yes, 2005
There is substantial research into genetic algorithms that are used to group large numbers of objects into mutually exclusive subsets based upon some fitness function. However, nearly all methods involve degeneracy to some degree.

Genetic profile of total body energy content of Holstein cows in the first three lactations [PDF]

open access: yes, 2005
Weekly total body energy content (TBEC) was calculated for 444 Holstein cows in their first 3 lactations. These calculations were based on body lipid and protein changes predicted from weekly changes in body condition score and live weight of each cow ...

GENETIC COVARIANCE OF FITNESS CORRELATES: WHAT GENETIC CORRELATIONS ARE MADE OF AND WHY IT MATTERS [PDF]

open access: yesEvolution, 1991
The genetic variance-covariance matrix, G, is determined in part by functional architecture, the pathways by which variation in genotype influences phenotype. I develop a simple architectural model for G for two traits under directional selection constrained by their dependence on a common limiting resource. I assume that genetic variance is maintained

Transethnic Genetic-Correlation Estimates from Summary Statistics [PDF]

open access: yes, 2016
The increasing number of genetic association studies conducted in multiple populations provides an unprecedented opportunity to study how the genetic architecture of complex phenotypes varies between populations, a problem important for both medical and ...

Accuracy of genomic selection for reducing susceptibility to pendulous crop in turkey (Meleagris gallopavo)

open access: yesPoultry Science, 2022
: Pendulous crop (PC) in the turkey occurs when the crop distends from its normal position, thereby preventing the movement of feed and water from the crop down into the digestive system.

A survey of genetic improvement search spaces [PDF]

open access: yes, 2019
Genetic Improvement (GI) uses automated search to improve existing software. Most GI work has focused on empirical studies that successfully apply GI to improve software's running time, fix bugs, add new features, etc. There has been little research into

Impact of breeding for reduced methane emissions in New Zealand sheep on maternal and health traits

open access: yesFrontiers in Genetics, 2022
Enteric methane emissions from ruminants account for ∼35% of New Zealand’s greenhouse gas emissions. This poses a significant threat to the pastoral sector.
