In particular, the dysgenic effects associated with two transposons, the “P factor” and “I factor” have been well documented (Engels, 1989; Finnegan, 1989). In each case, the effects are manifested when st

Such variation, it is believed, may be the raw material on which selection could bring about evolutionary changes in host usage. Because of t
