• Each lobe is dithecous, indicatin…

Dioecy & Heterostyly: Outbreeding Devices

Outbreeding devices are mechanisms or strategies employed by plants to promote outcrossing, which involves the transfer of pollen between different individuals within a population. Outcrossing enhances genetic diversity and reduces the risk of inbreeding depression. Various devices or mechanisms have evolved in plants to achieve outcrossing.

Dioecy

• Dioecy is a sexual system in plants where individual plants are either male or female, meaning they bear either m…
