microchaeta & scutum
Clones fail to differentiate epidermis. Microchaetes are densely packed and adjacent to one another. Macrochaetes are present as dense tufts of abnormal bristles.
Embryos homozygous for lethal gro mutations show highly variable neurogenic phenotypes with incomplete penetrance. This allele shows a weak neurogenic phenotype over Df(3R)Espl4.
