Genetic Mosaics and Chimeras: Implications in Biotechnology

  • M. Marcotrigiano
Part of the Biotechnology in Agriculture and Forestry book series (AGRICULTURE, volume 11)


Genetic mosaics are plants which are composed of tissues of two or more genotypes. They should not be confused with plant hybrids, which possess only one genotype; a genotype which is the product of recombination following fertilization. Mosaics can arise spontaneously or can be induced with chemical or physical mutagens. In mutagenized plants most of the mutant sectors arise outside the shoot apex (i.e., “extra-apical mosaicism”, described by Bergann 1967).
