Advantages of Genetic Transformation - 1. Symmetric hybrids can be produced between species, which can not be hybridized sexually.
2. Hybrids can be produced even between such strains, which are completely sterile, e.g., monoploids.
3. Cytoplasm transfers can be affected in one year, while back crossing may take 5-6 years.
4. Mitochondria of one species can be combined with chloroplasts of another species.
5. Recombinant organellar genomes, especially of mitochondria, are generated in somatic hybrids and cybrids. Some of this recombinant genomes may possess useful features.
