Features of Qualitative characters

  • Individual gene effect is quit large
  • Individual gene effect is detectable as it is large
  • Gene action working behind is mostly non-additive type i.e. epistastic or dominance gene interaction
  • Effect of environmental factors is very less as compared to quantitative characters
  • Stability of characters governed by one or some genes is comparatively high
  • Grouping of qualitative characters into different classes is possible as variation is discontinuous
  • Transgressive segregation is not possible with qualitative characters
  • Mendelian genetics or population genetics studies qualitative characters inheritance
