when using sas mixed cov test a genetic covariance component is the _____ of a trait which statement is best to use to estimate a covariance between traits sas avg covariance how to estimate covariance of sas genotype cl sas estimating between genotype how to get the coefficient of covariance how do I calculate the tlength of an genotype when you run a gene in sas, how to estimate between genotypes what is the covariance of a genotype is biomass a genotype how to obtain covariance in sas mixed sas estimating the variance of a trait how to estimate a covariance matrix for the genotype calculating the variance between a trait in sas how to get the covariance what is the covariance of biomass sas composite estimating covariance what is the covariance for genotypes if a trait in a trait is a genotype, sas estimates the covariance among the genotypes in the trait.
