Sexual reproduction is universally the main route to recombine genes in the short term; on the other hand, different strategies have been adopted to fix the genetic composition of individuals demonstrating high fitness. In plants, genotypes may be "immortalized" via vegetative propagation or "photocopied" by selfing of highly homozygous individuals. A third, more technically sophisticated pathway is represented by the implementation of apomixis, where a functional sexual machine is short-circuited to asexually produce embryos with the fixed genotype of the mother plant. This developmental sophistication represents a challenging research field for the reproduction biologist and a desirable trait for the plant breeder to be used in seed production schemes of elite varieties.Collection: Reprints Collection
