These are the hybrids which are formed as a result of the somatic hybridization. As a result of somatic hybridization, the nuclear and the cytoplasmic fusion occur and it is known as the product is known as the somatic hybrid. In certain cases, only the cytoplasmic fusion occurs which may be followed by the loss of any one of the nucleus. Thus the cell becomes uninucleated and such a fusion product is known as the cybrid or heteroplast.
