Genotype-environment interaction in the genetic variability analysis of reproductive traits in Nellore cattle
(Elsevier B.V., 2019-12-01)
The research aim was to evaluate the genotype-environment interactions (GxE) through a study of the reaction norms of Nellore cattle raised in the North and Northeast regions of Brazil at the age at first calving (AFC), ...
Reaction norms for the study of genotype-environment interaction for growth and indicator traits of sexual precocity in Nellore cattle
(Funpec-editora, 2015-01-01)
The objective of this study was to quantify the magnitude of genotype-environment interaction (GxE) effects on age at first calving (AFC), scrotal circumference (SC), and yearling weight (YW) in Nellore cattle using reaction ...
Reaction norm model to describe environmental sensitivity across first lactation in dairy cattle under tropical conditions
(2015)
Reaction norm models have been widely used to study genotype by environment interaction (G × E) in animal breeding. The objective of this study was to describe environmental sensitivity across first lactation in Brazilian ...
Genotype-environment interaction for age at first calving in buffaloes, using the reaction norm model
(Wiley-Blackwell, 2019-04-01)
Contents The objective of this study was to evaluate the genotype-environment interaction effect on age at first calving in buffaloes. The records were analysed using two approaches: (a) standard animal model and (b) ...
Phenotypic plasticity of composite beef cattle performance using reaction norms model with unknown covariate
(2013-02-01)
The objective of the present study was to determine the presence of genotype by environment interaction (G × E) and to characterize the phenotypic plasticity of birth weight (BW), weaning weight (WW), postweaning weight ...

Reaction norms of size and age at maturity of Pomacea canaliculata (Gastropoda: Ampullariidae) under a gradient of food deprivation
(Oxford University Press, 2009-02)
Pomacea canaliculata, an apple snail native to South America, has become a serious pest of aquatic crops and a promoter of ecosystem changes in natural wetlands worldwide. Its success as an invader has been attributed to ...
