Subject: Re: Helping FlyBase crep and oap Dear Dr Drysdale, crep is indeed allelic to mirror, as well as D1, D3,Sail1and Sail2. We therefore call the various alleles mirrD1, mirrSai1 or mirrcre1, mirrcre2 etc... For oap, we have separated by recombination the lethality from the P insertion which is in araucam. We keep the name oap for the lethal which is located between caup amd mirror. We are trying to obtain other alleles of it.
