Fig. 2From: The influence of QTL allelic diversity on QTL detection in multi-parent populations: a simulation study in sugar beetQTL effects illustration. a) cross-specific QTL: the allelic effects are different in every crosses due to some interaction between a QTL effect and the cross genetic background b) parental QTL: each parent carries a unique allele with consistent effect across the MPP c) ancestral QTL: parents inherit a reduced number of alleles due to shared ancestor. Each ancestral allele has a consistent effect across the MPP d) bi-allelic QTL: parent with the same SNP marker score are assumed to have inherited the same alleleBack to article page
