QTLs detected for developmental, male signal, and female receiver traits measured in brood Xt19.

See Table 1 for trait descriptions.Main effect QTLs determined via CIM mapping in Xt19, with additive effect (the estimated additive effect of the QTL is an estimate of the change in the average phenotype that would be produced by substituting a single allele of one type with that of another type) and R2 ( = proportion of phenotypic variance explained by the QTL after accounting for co-factors) shown in the two columns at the right. LG indicates the linkage group where the QTL is situated, marker interval is delimited by the two AFLP markers enclosing the QTL, and D is the distance, measured in cM, from the telomere to the QTL. PAres and PRres are the residual values.
