F2 Rosette-Dwarf, Non-Purple Stem

F2 Rosette-Dwarf, Non-Purple Stem

F2 Rosette-Dwarf variety of Wisconsin Fast Plants is the offspring generation of intermating the F1 Rosette-Dwarf. This stock (along with its F1 parental generation) demonstrates a two-gene inheritance model that is representative of Mendel’s findings.

F2 Rosette-Dwarf, Non-Purple Stem stock produces plants that show dihybrid segregation of normal height : dwarf plants and Purple Stem : Non-Purple Stem. This F2 Rosette-Dwarf, Non-Purple Stem stock can either be grown in potting mix through their life-cycles or germinated on paper towels and observed at 72-96 hours for phenotypes.

Phenotypes can be observed and quantified at 3 to 5 days. Second Generation (F2) expected 9:3:3:1 ratios are:

  • 9: Dark green leaves, purple stem
  • 3: Dark green leaves, non-purple stem
  • 3: Rosette-Dwarf, purple stem
  • 1: Rosette-Dwarf, non-purple stem

Genetic Designations:

  • ros/ROS, anl/ANL
  • anl/anl, ros/ros


  • Genetics: Inheritance studies, using both the F1 and F2 Rosette-Dwarf varieties to investigate two-gene inheritance patterns.
