Inheritance of differences in organs hairiness in Arabidopsis thaliana (L.) Heynh. Plants

It was determined that, according to the character «hairiness of rosette leaves», gl1-1 allele in homozygote state suppresses action of dis2-1 allele (dis2-1 < gl1-1), therefore F₂ segregation is identified in a typical for recessive epistasis ratio of 9:3:4. Inheritance of differences in hairiness of stem leaves corresponds to the Mendel scheme of segregation (9:3:3:1), which is typical for dihybrids. Hairiness is absent on stems of triple recessive for dis2-1, er-1, gl1-1 plants, and segregation in F₂ is observed in the ratio of 9:3:4.
