Embryos laid by heterozygous females are either lateralised, developing a cuticle with rings of ventral and lateral denticle bands. At gastrulation, embryos laid by heterozygous females fail to invaginate a ventral furrow and have a widened head fold. Embryos laid by eaD1/Df(3R)ea-5022rx1 females are markedly more elongated and have fewer denticle bands than embryos laid by eaD1/+ females.
Embryos have a lateralized phenotype: differentiate rings of ventral denticles around the entire dorso-lateral circumference and do not form the ventrally derived mesoderm. Heterozygous females are sterile.
