Donated by Muneo Matsuda (11/30/2003). The AABBg1 stock was established by Tobari and Kojima (1967) and has the 2nd chromosome homozygous for the standard arrangement, and the 3rd chromosome homozygous for ln(3L)A.
Chromosomes 2 and 3 were segregated at the University of Texas and donated to Moriwaki in 1951. In 1967, Tobari and Kojima made two inbred lines, AAAA and BBBB by pair mating for 10 generations. The AABBg1 was established by a single female hybrid from a mating pair between the two lines and F1 flies were repeatedly backcrossed to the BBBB strain for six generations: AABBg1 was established.
The stock was maintained as a small mass culture for 35 years until 2003 when it was inbred by single pair mating for two generations.
