      Homozygous hermat-1 and heterozygous hermat-1/her1 exhibit maternal-effect embryonic lethality, which both sexes affected equally.

      (ten Bosch et al., 2006)

      Daughters of her1/hermat-1 mothers are severely affected by the presence of a sisA point mutation and Sxlf9, viability can be restored by the presence of SxlM1. The presence of SxlfLS does not affect the daughters.

      (Pultz and Baker, 1995)

      Homozygous females are transformed to intersexes under restrictive and semi-restrictive temperatures (29oC and 25oC). Mutant males show a weak transformation to intersexuality in the sixth sternite has bristles. Surviving daughters of homozygotes and transheterozygotes raised at semi-restrictive temperatures show a high frequency of morphological defects not seen in sons. Maternal effect female lethality is enhanced by Sxlf1. Severely restrictive conditions (29oC for more than 2 days) reveals maternal sex-nonspecific lethality for all heteroallelic combinations except her3/her2 : embryos show defect in gastrulation and differentiation of the cuticles.

      (Pultz et al., 1994)

      Homozygous females produce 1 daughter to 5.5 sons. Abnormal sex ratio caused by inviability of females. l(2)mat does not seem to be allelic to da, which has a similar effect. RK3.

      Relative severity of the effects on female and male sexual differentiation is her3 > her1 > her2 > hermat-1. Relative severity of the effects on viability is her3 > her1 = her2 > hermat-1.

      (Pultz et al., 1994)

      Severely defective in maternal her functions but wild type in zygotic her functions.
