Genomic Selection Improves Response to Selection in Resilience by Exploiting Genotype by Environment Interactions
Genotype by environment interactions (GxE) are very common in livestock and hamper genetic improvement. On the other hand, GxE is a source of genetic variation: genetic variation in response to environment, e.g., environmental perturbations such as heat stress or disease. In livestock breeding, there is tendency to ignore GxE because of increased complexity of models for genetic evaluations and...
متن کاملCongress of Genetics Applied to Livestock Production The Effect of Using Genomic Breeding Values to Manage the Loss in Response to Selection Caused by Genotype by Environment Interactions
Genotype by environment (GxE) interaction can reduce genetic gain because there is often insufficient information for accurate selection in each environment. Genomic selection may be a useful method to reduce the impact of GxE interaction as measurement in different environments may be propagated over more selection candidates. We compared the value of testing the performance of relatives and/o...
متن کاملHost-parasite and genotype-by-environment interactions: temperature modifies potential for selection by a sterilizing pathogen.
Parasite-mediated selection is potentially of great importance in modulating genetic diversity. Genetic variation for resistance, the fuel for natural selection, appears to be common in host-parasite interactions, but responses to selection are rarely observed. In the present study, we tested whether environmental variation could mediate infection and determine evolutionary outcomes. Temperatur...
متن کاملGENOMIC SELECTION Genomic Selection in Multi-environment Crop Trials
Genomic selection in crop breeding introduces modeling challenges not found in animal studies. These include the need to accommodate replicate plants for each line, consider spatial variation in field trials, address line by environment interactions, and capture nonadditive effects. Here, we propose a flexible single-stage genomic selection approach that resolves these issues. Our linear mixed ...
متن کاملGenotype-by-environment interactions leads to variable selection on life-history strategy in Common Evening Primrose (Oenothera biennis).
Monocarpic plant species, where reproduction is fatal, frequently exhibit variation in the length of their prereproductive period prior to flowering. If this life-history variation in flowering strategy has a genetic basis, genotype-by-environment interactions (G x E) may maintain phenotypic diversity in flowering strategy. The native monocarpic plant Common Evening Primrose (Oenothera biennis ...
