how is artificial breeding more advantageous than natural breeding

. Polyploidy may be caused by fertilization of an egg by more than one sperm failure of meiosis during gamete formation. Polyploidy can artificially be introduced by a chemical called colchicine or by crossing diploids with tetraploids. Although triploids exhibit sterility, polyploidy is ..
