Xenia (plants)

With Xenie refers to the change in the genetics of the seed of a with respect to certain recessive genes plant, which shows the corresponding dominant hereditary characteristics of one parent because it is able to manifest in the endosperm as a result of fertilization of the secondary embryo sac nucleus.

The most common Xenia are probably the corn plant (Zea mays L.): If flowers of a yellow seeded race ( recessive gene ) are pollinated by pollen from a purple ( dominant gene ), this gives those mixed colored corn cobs, which for decorative purposes in floristry and for arrangements be used.

The term was coined in 1881 by the botanist Wilhelm Olbers Focke.
