Fate of Plasmagenes - In contrast to sexual hybrid cells, i.e., zygotes, which contain the plasmagenes from the female parent only, somatic hybrid cells, contain cytoplasmic complements from both the parental species.

The plasmagenes (generally studied in terms of chloroplast types or chloroplast DNA, cp-DNA) appear to be distributed randomly during the mitotic cell divisions.

As a result, some cells receive chloroplasts of one parental species; some others of the other species and a small proportion retain the chloroplasts of both the species. This is reflected in the plants regenerated from these cells. The same applies to mitochondria as well. In addition, the distribution of chloroplasts is independent from that of mitochondria.
