Segregation of A. cepa and A. roylei alleles in F2 generation. Application of single nucleotide polymorphism (SNP) markers enabled visualization of segregation distortion of the regions along individual chromosomes [linkage groups based on genetic map of Scholten et al. (2016)]. Statistically significant deviation from the Mendelian 1:2:1 ratio of rr:rc:cc genotypes was tested by multinomial test, separately for each SNP marker (P < 0.05; ∗∗P < 0.01; ∗∗∗P < 0.001). Two regions showing (statistically non-significant) distortion toward A. cepa alleles are highlighted with yellow color.
