N.  aThe genetic basis for constructing selection indexes.h[electronic resource]  c1943  aThe following constants must be known in order to solve the simultaneous equations: 1. Relative economic values for the different traits; 2. Phenotypic constants: a) standard deviations for each trait; b) correlation between each pair of traits; 3. Genetic constants: a) heritability of each trait; b) genetic correlations between each pair of traits.  aAnimal genetics  aBreeding and Genetic Improvement  aSelection criteria  aGenética Animal  aMelhoramento Genético Animal  aSeleção Genética  tGeneticsgv. 28, n. 6, p. 476-490, Nov. 943.
