Segregation of mutant alleles in the F₁ generation of the cross of pollen derived from Atrgtb1+/–Atrgtb2–/– on wt stigmaPollen derived from Atrgtb1+/–Atrgtb2–/– was crossed to wt stigma. Analysis of the genotypes in the F₁ generation was performed by binomial exact test against the H₀ hypothesis that segregation is Mendelian.
