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

Importance of apomixis in plant breeding? -Biology

Description : Importance of apomixis in plant breeding? -Biology

Last Answer : Apomixis produces seed progeny that are exact replicas of the mother plant. The major advantage of apomixis over sexual reproduction is the possibility to select individuals with desirable gene combinations and to propagate them as clones.
