Environmental sensitivity of Texel sheep estimated using reaction norms
MetadataShow full item record
The presence of genotype by environment interactions (GxE) can form a potential source of inefficiency in animal breeding if selection decisions are made without acknowledging their effects. As well as identifying the presence of GxE, the degree by which genotypes vary across environments is also of interest, which is often referred to as phenotypic plasticity or environmental sensitivity. Genotypes are considered “plastic” if they demonstrate highly variable phenotypes across environments or “robust” if they remain relatively constant, both of which can be calculated by reaction norm analyses. The objective of this study was therefore to quantify the effect of farm environment on the performance of Texel sire offspring.
