Figure 3.

Allele transmission ratio of Spiterstulen alleles from the F₁ to the F₂ for each parent, separately in male (light color) and female function (dark color), over all eight chromosomes. (A) Sp × Ma, (B) Sp × Pl, (C) Sp × Stu. F₁ parents with Sp cytoplasm are in blue (SpMaF₁, Sp1Pl1F₁, and SpStuF₁). MaSpF₁ is in red (A) and StuSpF₁ in green (C). The Sp2Pl2F₁ parent had cytoplasm from Sp but is represented in brown (B). The Mendelian expectation of equal segregation of both alleles, 0.5, is marked with a gray dashed line. The significant gametic TRD regions have been marked above the chromosomes as in Figure 2.
