WebFeb 1, 1998 · Well, not yet in terms of genes. I had come to Caltech to study the behavior of bithorax mutant cells in aggregates. My previous experience with other homeotic mutants, aristapedia and Antennapedia, was confusing (Garcia-Bellido 1968a). True, the homeotic leg cells of the antenna mixed well with leg and not with antenna cells, but the pattern ... WebJun 12, 2015 · For example, Ubx(Ultrabithorax) mutant embryos have their T3 and A1 segments transformed into T2, as if both the abx/bxand bxd/pbxsegment-specific functions were inactivated in Ubxalleles. In agreement with Ed Lewis’ observations, Ubxmutations fail to complement abx, bx, bxd, or pbxalleles.
