Question

The main drawback of self-pollination is that there is no ________________.

  1. Production of fruits
  2. Germination of seed
  3. Fertilization
  4. Gene mixing

hintHint:

Gene mixing

The correct answer is: Gene mixing


    In self pollination the purity of race is maintained as it increases genetic uniformity and decreases genetic variation which is similar to the parent plant as no gene mixing occurs.
