Table 2 QTL detected in the two independent and the combined pedigrees by the single QTL detection analysis with significance level <10%

From: Combining two Meishan F2 crosses improves the detection of QTL on pig chromosomes 2, 4 and 6

  1. Traits indicated in bold are common to the two independent pedigrees; LRT is the maximum Likelihood Ratio Test; the QTL effect is expressed in standard deviation units; the effect is given as Meishan - European alleles; +, *, ** are the 10%, 5% and 1% chromosome-wide significance levels respectively; the references of previously published data are given,/: when no previous result was available for this trait on the chromosome or when this QTL was not detected in the previous analysis.
