Subject: FlyBase query Dear Dr. Pointud, I am curating your abstract for FlyBase: Pointud et al., 1998, Int. J. Dev. Biol. 42(6): 29S 'Function of the bric a brac genes during adult ovary and leg morphogenesis.' in which you describe the isolation of two genes: bab-I and bab-II. At the moment FlyBase only has a record of one bab (bric a brac) gene. I would like to confirm whether either/both of your bab genes is the same as the bab already in FlyBase. Is the situation like polyhomeotic, where there are two duplicated copies of the polyhomoetic gene, ph-d (distal) and ph-p (proximal) ? If this is the case, I would be grateful for any information you may have about the molecular nature of the bab mutations already in FlyBase - do you know whether they are in bab-I or bab-II. I include a list of the bab mutations below (<up></up> = superscript), babE1 babP babPR10 babPR11 babPR23 babPR24 babPR30 babPR72 babPRDS I look forward to hearing from you, Gillian Millburn \-------------------------------------------------------------- Gillian Millburn. FlyBase (Cambridge), \-------------------------------------------------------------- > Subject: Re: FlyBase query Dear Dr. Millburn, The bab gene recorded in Flybase is the bab-I gene. The bab-II gene is at the same cytological location (61F) but is MOLECULARLY DIFFERENT of the bab-I gene. All the bab mutations in Flybase are in the bab-I gene.
