Symbol Chr.No Map Name Explanation Allele
Fem W ? female detemining gene
Fib-H 25 ? Fibroin H chain Spontaneous; structural gene of large subunit of fibroin; variations of mobility on SDS-PAGE grouped into fast, moderate and slow are controlled by Fib-HF, Fib-HM and Fib-HS. Fib-hF , Fib-hM , Fib-hS
Fib-L 14 ? Fibroin L chain Spontaneous; structural gene of small subunit of fibroin; variations in the order of mobility on SDS-PAGE as Fib-LA, Fib-LB, Fib-LC; no crossing over between Nd-s. Fib-LA , Fib-LB , Fib-LC
Fl 7 32.1 Flossy Spontaneous;cocoons are large and elliptic in shape with loosely composed shell; on flat surface larvae spin silk thread evenly in wide range to yield a uniform and high quality Sankenshi (raw-silk sheet). See also San.
fl 10 13 wingless Spontaneous;wings absent in pupae and moths; often die of bleeding from the uncovered border area between thorax and abdomen:flk(k無翅, k-wingless) and fln(n無翅) similar. flk , fln
flc 3 49 flimsy cocoon Spontaneous;cocoon shell very thin, large amount of fibroin granules retained in the glandular cells.
fs female sterile
Ga Green a Spontaneous;cocoon light green in combination with Gb.
gap 5 ? apterous and rudimentary gonads Spontaneous;pupae lack wings, thorax extremely narrow and slender; difficult in larval-pupal and pupal-adult ecdysis at head and thorax, ovaries undeveloped and sterile; larval growth tend to be retarded; locates in vicinity of oc. See also gon.
Gb 7 7 Green b Spontaneous;cocoon light green when combined with Ga or with Yf (locus unknown for both).
Gc 15 ? Green c Spontaneous;cocoon light green.
Ge 1 14 Giant egg Spontaneous;length and width of egg 1.26 and 1.11 times of the normal egg, respectively, hatched larvae bigger and heavier; hatchability reduced: Ge2 allele larger egg size. Might be translocation of Esd on the W chromosome. Ge2
ge 12 ? geometrid Spontaneous;larval body slender, weakly constricted at second abdominal segment anteriorly and posteriorly.
Gl 19 19.2 Glossy Spontaneous;larval skin tinged reddish brown and lustrous at GlR
gn 9 22 gooseneck γ-ray induced;larval body slender and constricted between the segments: gnd(細節蚕d, gooseneck distinct) spontaneous allele of more distinct constriction. gnd
gon 18 ? undevelopped gonads Spontaneous;newly hatched larvae colored whitish ~ reddish brown; larval growth tend to be retarded, apt to produce cf-like pupae with protruded wings; both testes and ovaries not developed well remain small like those of third or fourth instar larvae, though other reproductive organs not only external but also inner as accessary gland, vas deferens, seminal vesicles, oviducts, ovipositor, mucous gland, etc. fully developed; gametes scarcely develop to secondary gonia; locates in close vicinity of elp. See also gap.
Gr 2 9.9 Gray egg Spontaneous;egg shape ellipsoidal; chorion translucent and colorless in eggs laid by homozygous mother moth, opaque and milky white in heterozygote’s eggs: Spontaneous alleles as Gr16(欧16灰色卵, E-16 gray), GrB(鳥眼卵,Bird’s eyed gray), Grcol(潰れ卵,collapsing), Grk(桂灰色卵, Kei's gray); Xray induced alleles as GrL(淡灰色卵, Light gray), GrX-1(X線誘発灰色卵, Gray egg X-1), GrX-2(第2X線誘発灰色卵, Gray egg X-2). Gr16 , GrB , Grcol , Grk , GrL , GrX-1 , GrX-2
gr-r 2 10.5 recessive grey egg
Grc Green cocoon
Gre 1 46.4 Green egg shell Spontaneous;egg shell tinged yellowish green.
