MSE values^aof QTL position estimations for the three methods in a chromosomic region of 25 cM, with two-marker densities, applied to a half-sib designs^b (1000 progeny in total)

^aMSE, mean square error (cM²). Standard errors in parentheses.

^bBonferroni t test. MSE values with the same letter are not significantly different. First letter, differences between methods; second letter, differences between family numbers; third letter, differences between marker densities.

^cModels: LA, linkage analysis; LDLA_reg, LDLA analysis by regression model; LDLA_vc, LDLA analysis by IBD variance component model.
