      Generated using the Loua 83 P-strain.

      (Brookfield and Mitchell, 1985)

      Some somatic reversion of this allele, generating mosaics having patches of cuticle with a wild-type phenotype, is seen. The rate of somatic reversion is 0.06%. The movements of the P-elements in these somatic reversions occur early in development, and require a trans-acting maternal effect component (P\TMo). Somatic reversion occurs preferentially in attached-X stocks.
