Question

Describe the outbreeding devices that prevent the autogamy.

Answer 1

Outbreeding defines the process in which the mating of the animals is performed which belongs to the different breed. This technique helps in preventing self-pollination and inbreeding depression. The devices which are used to prevent autogamy are:

• The male and the female reproductive organs in the flower do not get matured at the same time (protandry and protogyny).
  
• The male and the female flowers are present on the different plants (monoecious).
  
• The stigma of the female flower does not recognise the pollen from the anther of the flower on same plant (self-incompatibility)
