Fig. 3: Progeny SC-index by S-genotype for between breeding system (BBS) crosses (♀SI × ♂SC and ♀SC × ♂SI).

Panel a and b show progeny from crosses with maternal (a) or paternal (b) SC partners homozygous for S1 associated with B80H50. Panel c and d show progeny from crosses with maternal (c) or paternal (d) SC partners homozygous for S19 associated with B80H75. S-genotypes were inferred by known linkage to B80 sequences as indicated in the figure (also see Supplementary Data 1). S1 and S3 are recessive to all other known S-alleles, and S3 is dominant over S1. Putatively expressed S-alleles are given in black, nonexpressed (recessive) S-alleles in grey. Sx represents several S-alleles different from S1, S3, or S19 (see legend for details). Source data are provided as a Source Data file.
