“…As a comparison, breeding programmes for livestock animals generally make use of traits with higher heritability. Heritability values for morphological, physiological, behavioural or other traits linked to fitness and considered in these breeding programmes generally range from 0.17 to 0.70 in sheep, pigs, cows and fish(Juengel et al, 2019;Kavlak & Uimari, 2019;Moretti, de Rezende, Biffani, & Bozzi, 2018; Vargas Jurado, Leymaster, Kuehn, & Lewis, 2016). However, in order to select traits with low heritability values, the method of genomic selection is already used for livestock animals (e.g Hayes, Bowman, Chamberlain, & Goddard, 2009)…”
