Induced Mutations and Polyploidy Breeding
Mutation is a sudden heritable change that occurs in the genetic information of an organism not caused by genetic segregation or genetic recombination but induced by chemical, physical or biological agents. Polyploids are organisms with multiple sets of chromosomes in excess of the diploid number. Polyploidy is a natural mechanism that provides adaptation and speciation.
