Research paper

The yield of spontaneous Minute mutations was recorded in the F1 progeny of interstrain (reciprocal) and intrastrain matings between a recombination- and excision repair-defective mei-9L1 (mei-9) strain and the y w m f/sc8(y+) Y BS; dp (ywmf-2) strain of Drosophila melanogaster. As a comparison, interstrain matings between a postreplication repair-defective st mus(3)302D1 (mus(3)) strain and the ywmf-2 strain were also studied for Minute mutations. The results show that: (1) a strikingly high frequency of Minute mutations is observed in the progeny of mei-9 female X ywmf-2 male crosses, but not in that of ywmf-2 females X mei-9 males; (2) no such difference exists in the progeny of intrastrain matings; and (3) there exists no marked inequality of Minute frequencies in the progeny of reciprocal crosses of mus(3) and ywmf-2 strains.
