9088bp roo element inserted in the 3' intergenic region downstream of L. Present in a number of dominant L mutant alleles isolated around 1920, but also present in the ft1 chromosome isolated during the same time period, suggesting that it is probably not related to the dominant L mutant eye phenotype. Not the same as roo{}828; roo{}Mohr is 261bp proximal to the location of roo{}828.
