Level-biases in estimated breeding values due to the use of different SNP panels over time in ssGBLUP

Table 2 Accuracy and regression coefficients of genomic predictions as well as a measure of level-bias between genotyped vs. non-genotyped animals

For Scenarios 1 to 4, the standard errors due to the random sampling effect of SNPs are in parentheses
^aScenarios described in Table 1
^bRegression coefficient \(\beta\) from the linear regression with YD as a response variable and the GEBV as an explanatory variable
^cLevel-bias is measured in genetic standard deviations
