Mutable systems possess transposable elements that cause mutability of associated gene loci. The En system (composed of I and En) was used to test the induction of mutability of two selected loci, A2, and C possessing the normal alleles. In a test of over five million gametes one mutable was found at each of the selected sites as well as two others, both dominant and non-allelic to the selected sites. It appears that this low rate of induction of mutability (as compared to other reports) is a consequence of the non-randomness of site selection; i.e., a certain physical chromosomal continuity abets the transposition of elements to selected sites.
