Spontaneous;serosa cells light yellowish brown, larval skin weakly translucent, compound eye black: Alleles causing white egg and translucent larval skin to various degrees depending on the uric acid contents in hypodermis: w-3b(brown egg 3; cancells maternal inheritance of w-1): w-3ml(melamine induced oily and white egg): w-3oe(white-egg translucent; not only eggs but also compound eyes white, larvae highly translucent): w-3ol(aojuku white-egg translucent, like w-3oe), and so on: Interaction between non-allelic translucent genes varies, uric acid contents in epidermis are 1:w-3 > od > od w-3 > w-3oe > od w-3oe, 2:w-3 > oa > w-3oe > oa w-3 > oa w-3oe, 3:w-3 > os > os w-3 = os w-3oe >w-3oe.
