Features of Quantitative characters

  • Individual gene effect is very small
  • Individual gene effect is undetectable as it is small
  • Gene action working behind is mostly of additive type
  • Effect of environmental factors is more as compared to qualitative characters
  • Stability of characters governed by many genes is comparatively low
  • Grouping of quantitative characters into different classes is not possible as variation is continuous
  • Transgressive segregation may occur with quantitative characters
  • Biometrical genetics or quantitative genetics studies quantitative characters inheritance
