How might the ability of pea plants to self fertilize be a problem for genetic experiments?

#Part-B Specialized Branches in Biotechnology
  1. Self fertile plants tend to be weaker and require more care.
  2. Self fertile plants are not able to produce viable seeds due to inbreeding.
  3. Stamens must be removed from self fertile plants to control fertilization 
  4. Pistils of self fertile plants are unable to accept pollen from other plants.
