A species concept based on cladistics that does not insist on monophyly. It recognizes species pairs one a monophyletic daughter species (apospecies) and the other a paraphyletic progenitor species (plesiospecies).

(AP-PCR)A variant of the Random Amplified Polymorphic DNA (RAPD) technique that uses longer arbitrary primers than RAPDs.

The formation of new individuals from the cell(s) of a single parent. It does not entail recombination or mixing of parental forms.

A research field directed to the identification of correlations between phenotypic traits and genetic markers with the aim to identify and locate the underlying genes in the genome.

Transfer of pollen (pollination) from the anther of a flower to the stigma of the same flower or sometimes to that of a genetically identical flower (as of the same plant or clone) The ability of many plant species to naturally and successfully fertilize within one individual. Also called self-pollination.
