B-A stocks are named for the translocation present. B-A chromosomes are marked with either a color factor (A1, A2, B1-peru, Bz1, Bz2, C1, C2, Pr1,or R1-scm2) or an autonomous transposable element (Ac or Dt). Except for the recessive color factor indicated above, each tester stock was homozygous for A1, A2, b1, Bz1, Bz2, C1, C2, Pr1, and R1-scm2. Several testers had color factors that possessed insertions of a nonautonomous transposable element (Ds or rdt).
