Continued self-pollination results in
Inbreeding depression
Out breeding depression
Hybrid vigour
Better result in offsprings
The phenomenon in which, anther and stigma grow and mature at same time is called
$A$ : Continued self-pollination checks inbreeding depression.
$R$ : Pollen release and stigma receptivity are synchronised.
The maturation of male (anthers) and female (stigma) structures at different times in the same flower (in order to reduce the possibility of self pollination) is called
Give scientific reasons : Outbreeding devices increase fertility.
