ABSTRACT The objective of this study was to unravel the genetic architecture of growth traits in sheep through a meta-analysis of genetic parameters (i.e., direct, maternal, and total heritability estimates, as well as genetic correlations), a systematic review, and a functional analysis to identify candidate genes and metabolic pathways related to growth traits. A random effects model was used to obtain the pooled effect estimates for the genetic parameters, and heterogeneity was assessed using both I2 and Cochran’s Q statistics. […]
