  • a In the RI population, QTL effects were associated with the Lemont allele (due to replacement of the Teqing allele by the Lemont allele). In the BC populations, QTL effects for F1 and HMP were estimated by the heterozygote minus the homozygote. The genetic expectation of a QTL effect obtained is the additive gene effect (a) when estimated from the RI, the additive and dominance effects (a + d) from the F1 mean values, and the dominance effect (d) from HMP values.
