Additional file 4: of Evidence of epistatic suppression of repeat fruiting in cultivated strawberry

Table S4. Calculations of segregation ratios for progeny families from all possible phenotype/genotype parental combinations for a two-locus model to explain repeat fruiting vs once-fruiting of strawberry. Calculations assume the primary, already mapped locus, has a dominant allele (RB) conferring repeat fruiting, and a recessive allele (jb) conferring once-fruiting. Repeat-fruiting parental and progeny phenotypes are highlighted in dull yellow, and once-fruiting phenotypes are highlighted in pale green. On the left of the grey vertical bar are calculations that assume the presence of a second locus with a completely dominant allele (STOP) conferring epistatic suppression of the mapped locus when homozygous (STOP STOP) or heterozygous (STOP stop), and a recessive allele (stop) that does not affect the mapped locus). On the right of the grey vertical bar are calculations that assume the presence of a second locus with a recessive allele (stop) conferring epistatic suppression of (or failure to support) the mapped locus when homozygous (stop stop), and a completely dominant allele (STOP) that does not change the phenotype conferred by the mapped locus. Horizontal grey and purple bars separate different genotypic parental-combination possibilities for similar phenotypic possibilities. Resulting progeny phenotypes are characterized as repeat-fruiting (RB) or once-fruiting (jb) similar to the mapped locus. Expected resulting segregation ratios are highlighted in bright yellow boxes.

补充表S4：针对草莓重复结实与单次结实性状的双基因座模型，计算所有表型/基因型亲本组合的后代家系分离比。本计算设定已定位的主效基因座包含两个等位基因：显性等位基因RB（赋予重复结实表型）与隐性等位基因jb（赋予单次结实表型）。重复结实的亲本及后代表型以暗黄色标注，单次结实表型以淡绿色标注。灰色竖线左侧的计算假设存在第二个基因座，其完全显性等位基因STOP可在纯合（STOP STOP）或杂合（STOP stop）状态下对已定位座位产生上位性抑制，而隐性等位基因stop不对已定位座位产生影响。灰色竖线右侧的计算则假设存在第二个基因座，其隐性等位基因stop可在纯合（stop stop）状态下对已定位座位产生上位性抑制（或无法维持其表型），而完全显性等位基因STOP不会改变已定位座位所决定的表型。横向灰色与紫色条带用于区分具有相似表型可能性的不同基因型亲本组合类型。所得后代表型依据与已定位座位一致的性状特征，分为重复结实型（RB）与单次结实型（jb）。预期分离比以亮黄色方框标注。（XLSX格式，文件大小235 KB）
