Epigenetic regulation of transposable elements in the plant kingdom which allows for self-copying) within the coding of the transposon defines class I elements as autonomous or non-autonomous. Class I transposons can take the form of: Curiously, retrotransposons have been discovered to be the predominant form of transpositional element in plants with large genomes, such as maize and wheat, potentially indicating rapid success of this class of transposon in the creation of hybrids, such as wheat, peppermint and, in the distant past, maize. Plant hybridization often creates polyploids, with double, triple, quadruple or more the number of chromosomes present in the parent generation. Polyploid hybrids seem to be particularly susceptible
USA Broadcasting also briefly owned four Fox affiliate stations, formerly owned by SF Broadcasting: WLUK (Green Bay, Wisconsin), KHON (Honolulu, Hawaii), WALA (Mobile, Alabama), and WVUE (New Orleans, Louisiana). That ownership was between 1996 through 1998, before the four stations were sold to Emmis Communications.
