Segregation distortion patterns in two independent white clover F
mapping populations. Data are -log10P for female (♀)-derived alleles; log10P value for male (♂)-derived alleles for white clover mapping populations MP1 (dashed line) and MP2 (solid line). Distorted loci were declared at P<0.05 (log10P>±1.3) and aligned as a proportion of distance along each integrated linkage group for each of the two homoeologues (H-1, H-2), noting that -1 and -2 are arbitrary distinctions and do not relate to the progenitor genomes O and P’ of T. occidentale and T. pallescens, respectively. The Self-Incompatibility (S) locus  is on the top end of group 1, and may underlie the severe male-derived distortion observed in MP2 on that group.
