Genotype gametophyte

Genotypes of gametophytes individuals identified (based on diagnostic microsatellite, ITS1 and species-specific cytoplasmic marker) as E. siliculosus (Esil, n = 158) and E. crouaniorum (Ecro, n = 176). This identification was used previous to the admixture analyses. The number of samples in each population, name of the strain, ITS1 length (850 = Esil, >1000 = Ecro) and positive amplification in the cytoplasmic marker (Esil = positive amplification Esil, Ecro = positive amplification Ecro) are shown. In diagnostic loci, the non-amplification in one of the parental species corresponds to a phylogenetic signal but should be distinguished from a null allele. To solve this problem, these missing data points were replaced by an artificial allele of an arbitrary size of (800bp). In contrast, missing data or null alleles were noted as 0.
