  • a Hypocotyl lengths in millimeters.

  • b t-test and P value from comparing the phyB1/phyB-1 shy/shy and phyB-1/phyB-1 SHY/shy seedling hypocotyl lengths. The low P values indicate that for all of the mutations, the hypocotyl length of the shy/shy homozygote is significantly shorter than that of the SHY/shy heterozygote, and that therefore none of the shy mutations is completely dominant.

  • c t-test and P value from comparing the phyB1/phyB-1 SHY/SHYand phyB-1/phyB-1 SHY/shy seedling hypocotyl lengths. For the phyB-1/phyB-1 SHY/SHY single mutant, the hypocotyl measurements were x = 9.9, σ = 1.5, and n = 140. The results indicate that only shy3-1, pom114, shy2-2, and shy2-3 heterozygotes are significantly shorter than the phyB-1/phyB-1 single mutant and, therefore, are not recessive.
