Berry (botany) fruits, the edible part is not generated by the ovary. Berry-like examples include: The female seed cones of some conifers have fleshy and merged scales, giving them a berry-like appearance. Juniper "berries" (family Cupressaceae), in particular those of "Juniperus communis", are used to flavour gin. The seed cones of species in the Podocarpaceae and Taxaceae families have a bright colour when fully developed, increasing the resemblance to true berries. The "berries" of yews ("Taxus" species) consist of a female seed cone with which develops a fleshy red aril partially enclosing the poisonous seed. The Latin word ' or ' (plural
Flavour (particle physics) description of the flavour symmetry is described by a chiral group . If all quarks had non-zero but equal masses, then this chiral symmetry is broken to the "vector symmetry" of the "diagonal flavour group" , which applies the same transformation to both helicities of the quarks. This reduction of symmetry is a form of "explicit symmetry breaking". The amount of explicit symmetry breaking is controlled by the current quark masses in QCD. Even if quarks are massless, chiral flavour symmetry can be spontaneously broken if the vacuum of the theory contains a chiral condensate (as it does in low-energy
