The heterostyly is genetically a flower polymorphism controlled where populations of plants present two or three morphs, that in natural areas in balance, it hopes to meet a same reason among the morphs (isoplethy). Those morphs are shown inside with reproductive pieces in different heights of the flower, in other words, with a space separation among anther/stigma, denominated herkogamy. In most of the species distylous, the herkogamy is usually shown in a reciprocal way. As larger the herkogamy smaller intrafloral the direct interference among the pieces sexual, and smaller the deposition of self pollen in the stigma, reducing the conflict among the sexual organs, in hermaphrodite flowers. The heterostyly is one of the characteristics more...
