X Chromosome balancers at Bloomington
All useful balancers for the X chromosome found in Bloomington stocks are included here (at least that is the intention), but only one or a few stocks that we consider to be generally useful as a source of each balancer are shown. Use the Search option to find all possible stocks that carry a given balancer.

With a few exceptions to support searches, only markers that vary from those defined by the core balancer symbol (FM7, CyO, TM3, etc.) are shown in the genotype. See Balancer Definitions for a description of the aberrations and markers defined by each balancer symbol used in the Bloomington stock list.

Not all balancers are equal! See An Introduction to Balancers for an explanation of how to choose a good balancer.
