Segregation distortion increases the frequency of MAF2 insertion alleles in the progeny ratio. (A) Segregation distortion observed in BC₅ F₂ populations segregating for various MAF2 insertion alleles and MAF2–Ler. MAF2 insertion allele homozygotes are dark shaded bars, plants heterozygous for a MAF2 insertion allele and MAF2–Ler are light shaded bars, and MAF2–Ler homozygotes are shown as open bars. (B) Segregation distortion of MAF2 and FLC alleles observed in the BC₄ F₂ progeny of MAF2–UWO in Ler × FLC-Col in Ler. MAF2–UWO homozygotes are dark shaded bars, MAF2–Ler homozygotes are shown are open bars, and heterozygous plants are light shaded bars. FLC–Ler homozygotes are dark shaded bars, FLC-Col homozygotes are open shaded bars, and heterozygous plants are light shaded bars.
