E 6 21.1 Plain extra-legs Individuales with this gene affects supernumerary or deficient legs on specific segments along with abnormalities in the position and number of the prominent paired crescent markings on abdorminal segment 2, and stars on 5. So far, about 40 or more mutants manifesting similar traits have been discovered. Genes of those have been mapped at 21.1 CM of 6th linkage groups, however they often had crossing over event at very low frequency. Hence, they are called E-pseudo-allelic gene group.
According to exsperiments of some mutant in those, this E locus have been identified as the silkworm homologue of the bithorax homeotic gene complex of D. melanogaster.
Many are embryonic lethals as homozygotes and exhibit abnormalities in tracheal patterns, cocoon shapes, gonad development and wings.Spontaneous; Rudimentary crescents and extra abdominal legs on fourth and fifth segments star spots present.

EAl 6 21.1 Extra-abdominal legs and extra crscents Spontaneous; extra legs on 4th and 5th segments, additional crescents on 4th segment. Homozygous moths predominantly sterile in both sexs. Allele Of E
ECa 6 21.1 Additional crescents Spontaneous; Additional crescents on 6th segment, star spots absent. Homozyous embryo lacks abdominal legs, lethal. Allele Of E 3
ECd 6 21.1 Cd-double crescents X-ray induced; additional crescents on 4th segment. Homozygous absent abdominal legs, lethal. Allele Of E 1
ECl 6 21.1 Double crescents and supernumerary legs MNU induced; additional crescents on 4th segment, supernumerary legs on 4th and 5th segment. Homozygous lethal. Allele Of E 1
ECn 6 21.1 Additional crescents and no star Spontaneous; like Eca, additional crescents on 6th segment not completely. Homozygous lethal. Allele Of E 1
ECs 6 21.1 Supernumerary crescents and legs Spontaneous; additional crescents on 6th segment, supernumerarylegs on 5th segment, no star. Allele Of E 1
ECt 6 21.1 Ct-triple crescents X-ray induced; additional crescents on 4th and 6th segments, supernumerary legs on 4th and 5th segments. Homozygous lethal. Allele Of E 1
ECw 6 21.1 Extra-crescents and extra wings Spontaneous; additional crescents 6th segments.Homozygous have extra legs on 4th and 5th segments, extra legs on 5th segment not completely. Moths show extra wings and legs on 1st segment. Allele Of E
ED 6 21.1 Double crescents Spontaneous; Extra crescents on 4th segment, seldom supernumerary legs present on 4th and 5th segments. Extra legs on 4th segment like thoracic legs. Spiracles on 4th segment small, rarely lacked. Third and 4th segment frequently fused. Hind wing small and XXX, hind legs deformaed. Homozyous lethal. Allele Of E 1
EDc 6 21.1 Dc-double crescents X-ray induced; additional crescents on 4th segment. Homozygous semi-lethal. Allele Of E
EDl 6 21.1 Extra-crescents and degenerated abdominal legs Spontaneous; homozygotes have extra crescents on 6th segment, lack star spots, and 1st abdominal legs on 6th segment rudimentary. In heterozygotes, extra crescents deformed but spots manifested on 8th segment. Allele Of E 1
EDn 6 21.1 Double crescents and no star High temperature induced; additional crescents on 6th segment, lack star spots. Homozygous lethal. Allele Of E
EDs 6 21.1 Double stars Spontaneous; extra star spots on 7th segment. Homozygous lethal. Chromosome translocation berween 6th and 7th linkage groups. Allele Of E 1
EEl 6 21.1 Extra-crescents and extra-legs Spontaneous; Additional crescents on 4th segment, small abdominal legs on 4th and 5th segments.Homozygous lethal just before hatching. Allele Of E 2
EEn 6 21.1 New extra-crescents and extra-legs Spontaneous; like EEl, but no star spots, homozygous lethal. Allele Of E 1
EGd 6 21.1 Deformed gonad Chemicals or temperature shock; Additional crescents on 4th segment, supernumerary legs on 4th and 5th segments.Pupal wing shortened.Wings of adult splitted, hind legns of homozygous adult degenerated, accompanied with abnormality of gonads. Supernumerary crescents and abnormality of gonads dominant, while abnormality of legs and wing recessive. Allele Of E 1
EH 6 21.1 H-extra-crescents Spontaneous; Extra legs on 4th segment but frequently incomplete.Semi-lethel. Allele Of E 1
EHm 6 21.1 Himenichi extra-legs Spontaneous; additional legs on 5th segment. Homozygous reveal supernumerary crescents on 6th segment. Allele Of E
EKa 6 21.1 Ka-additional crescents Spontaneous; supernumerary crescents on 4th segment. Additional legs rarelyappear on 4th and 5th segments.Homozygous lethal. Allele Of E 1
