Summary
We have studied the influence of some mutations in the bithorax complex on the observed synapsis dependent phenotype of the genotypes Cbx 1Ubx1/+ and bx 34e/Ubx1. The effect of these mutations is similar to that introduced by disruption of pairing or by the z a mutation. Among the bx mutations, we find that bx 8 behaves differently from most other bx mutations in its influence on the synapsis dependent phenotype. This observation induced us to map the position of bx 8 with respect to other bx mutations; we find that it maps between bx 34e and bx 3. We show how some of the observations reported here can be fitted into a model of activation of the bithorax complex proposed by one of us.
