Polytene chromosomes normal.
Heterozygotes with DoaHD survive rarely and when they do, wa is darkened to nearly wild-type color; wsp55 reacts in the opposite manner, becoming nearly white; eyes of escapers have disarranged facets. Males of these heteroallelic combinations involving Doa6 are sterile despite having motile sperm; females weakly fertile.
Rare DoaHD/Doa6 escapers show extreme suppression of the wa phenotype, such that eyes, Malpighian tubules, ocelli and testes are essentially wild-type in colour. They have disordered eye facets and scutellar bristles are often missing or abnormal. Male escapers carrying wsp55 have bleach-white eyes.
Does not interact with gypsy induced alleles at several loci (f1, y2 and ct6).
