Data represent offspring from 15 litters collected at E17.5. Mice lacking the Ella-Cre transgene showed no recombination of the Irf6fl allele. Mice carrying the Ella-Cre transgene showed mosaic recombination of Irf6fl. Some offspring showed no recombination (Irf6fl only), presence of both the Irf6fl and Irf6nl alleles, or complete recombination (Irf6nl only).
