Define induced polyploidy. Explain two applications of polyploidy.

Induced polyploidy refers to the process of artificially increasing the number of sets of chromosomes in an organism. Polyploidy occurs when the number of chromosome sets in a cell exceeds the normal two sets (diploid). In nature, polyploidy can occur spontaneously through errors in cell division, but induced polyploidy is achieved through laboratory methods. This is typically done using chemicals such as colchicine or oryzalin, which interfere with the normal process of cell division, particularly during mitosis or meiosis. These chemicals block spindle fiber formation, preventing the separation of chromosomes during cell division and thus leading to the doubling of chromosome sets in the resulting cells. Induced polyploidy can create organisms with multiple sets of chromosomes, which may _______ _______ ____ _________ ___ ______ ________ ___ _______ ___ _____.
