Explain Three Outbreeding Devices -

1. In some species , pollen is released before  the stigma becomes receptive or stigma becomes receptive much before the release of pollen.

2. 
In some other species, the anther and stigma of the same flower.

3. The third device to prevent inbreeding is self-incapability . This is a genetic mechanism and prevents self-pollen from fertilizing the ovules by inhibiting pollen germination or pollen tube growth in the pistil.
