      Phenotypic category: ovoreduced svb-

      (Garfinkel et al., 1992)

      Phenotypic category: svb-.

      (Lindsley and Zimm, 1992)

      Most of the egg chambers of homozygous females develop into eggs that are laid (more than 30% of the wild-type number of eggs are laid per day). The eggs are usually permeable to neutral red and have fused appendages. Hemizygous larvae have few denticle belt setae. Transheterozygotes with either ovoD2 or ovoD3 have germ cells resembling early spermatocytes.

      (Oliver et al., 1990)

      Gene activity not detectable. Male germ line is fertile, female germ line has no vitellogenic egg chambers.
