Two contrasting interpretations of the diversity detected in the experimental volunteer population: example with two triallelic loci. For each locus, one allele (a and b here) is approximately in frequency 50%. (a) F1-hybrid variety with a polymorphic parental line (PL). Three parental haplotypes are present. When fusing alleles A1 and A2, and alleles B1 and B2, the situation is equivalent to the basic model. (b) Mixture of two F1-hybrid varieties. One supplementary parental haplotypes (aB2) is present, although rare. It is not detected by the linkage disequilibrium analysis because it is masked by the more frequent haplotype ab. When fusing alleles A1 and A2, and alleles B1 and B2, the structure of the initial state deviates from the assumptions of the model.
