Answer 1

Hi mate.


Thanks for asking this question.



Here is your answer,



$outbreeding \: divices \: =$


Majority of the flowering plants can

produce a hermaphrodite or bisexual flower

and their pollen grains are comes in contact

with the stigma of the same flower. The

continuous flow of self-pollination results in

inbreeding depression.




Therefore, the flowering plants provided

a many devices to encourage cross-pollination

and to discourage self-pollination.




The plants of the some species,

pollen grains released on stigma is not

synchronize ( anther and stigma opens at

same time) .




In some other species, the stigma and

stigma are placed at different positions so the

pollen grains does not comes in contact with

the stigma of the same flower.





BOTH THESE DEVICES PREVENTS AUTOGAMY.





THANK YOU.
