Apomixis Evolution, Mechanisms and Perspectives

About this book

Apomixis (asexual reproduction without fertilisation) is no longer regarded as a 'blind alley' of evolution, but rather as an alternative mechanism to the predominant sexual pathway, and that needs to be explored in many details to fully understand its role in nature.
