Mariner, Mos and associated aberrant traits in Drosophila mauritiana.
A suite of aberrant genetic traits, including increased mutation rate, sex-limited mutation and distorted transmission ratios, was produced among progeny of genetic crosses between two strains of Drosophila mauritiana when a paternally contributed Mos excision factor is placed into a non-Mos genetic background. In the reciprocal cross, involving maternally contributed Mos and Mos associated cytoplasm, the same genetic abnormalities are not observed. Differential effects on mariner excision in germ-line versus somatic tissue are apparent. Because Mos is known to influence the mobility of the mariner transposable element, these traits may be associated with mariner excision and/or transposition.
