We generated FM7a and CyO balancer chromosomes bearing a Tubby(1) (Tb(1)) dominant transgene.

Abstract

We generated FM7a and CyO balancer chromosomes bearing a Tubby(1) (Tb(1)) dominant transgene. Flies heterozygous for these FM7a and CyO derivatives exhibit a phenotype undistinguishable from that elicited by the Tb1 mutation associated with the TM6B balancer. We tested two of these Tb-bearing balancers (FM7-TbA and CyO-TbA) for more than 30 generations and found that the Tb1 transgene they carry is stable. Thus, these new Tb-tagged balancers are particularly useful for balancing lethal mutations and distinguish homozygous mutant larvae from their heterozygous siblings.
