Inheritance of two body color mutations of the spiny bollworm (Earias insulana)

Reciprocal crosses in all possible combinations between the yellow-green (YG) wild line and two body color mutations — viridian-green (VG) and grayish-white (GW) — of the spiny bollworm,Earias insulana (Boisd.), indicated that these mutations were not sex-linked or controlled cytoplasmically. The YG phenotype was dominant over both body color mutations. A genetic model involving two genes with recessive epistasis is proposed for the inheritance of body color.
