Reduction or absence of dorsal appendages (ventralization) with increase in main body egg shell. Micropyle at both ends of eggs, embryos ventralized.
An enlarged mass of mesodermal cells invaginates on the ventral side of the embryo, the enlarged mesoderm is often organised into two ventral furrows. Organisation is lost in later stages of development and a mass of mesodermal cells fills the ventral half of the embryo. Respiratory appendages are completely absent and only the ventral most portion of the operculum is present.
phenotype of eggs and embryos: intermediate and strong
Strong grk allele.
