  • 1. 
    After cross-fertilization of true-breeding tall and dwarf plants, the F

  • 1:2:1 (homozygous tall : heterozygous tall : dwarf)
  • 1:2:1 (heterozygous tall : homozygous tall : dwarf)
  • 3:1 (tall : dwarf)

  • 4. 
    If both genotype and phenotype shows the same ratios of 1:2:1 in the F

  • 5. 
    Test cross determines
