Self pollination will lead to – (1) inbreeding (2) rare breeding (3) overbreeding (4) outbreeding

Description : Self pollination will lead to – (1) inbreeding (2) rare breeding (3) overbreeding (4) outbreeding

Last Answer : (1) inbreeding Explanation: Self-pollination can lead to inbreeding depression, or the reduced health of the species, due to the breeding of related specimens. This is why many flowers that could potentially self-pollinate have a built-in mechanism to avoid it.

What is apomixis in plant breeding? -Biology

Description : What is apomixis in plant breeding? -Biology

Last Answer : Apomixis (asexual seed formation) is the result of a plant gaining the ability to bypass the most fundamental aspects of sexual reproduction: meiosis and fertilization. Without the need for male fertilization, the resulting seed germinates a plant that develops as a maternal clone
