clearwing การใช้

• The Clearwing Skyblue is similar but with a blue body and white wings.
• Another rare invertebrate is the orange clearwing moth.
• The Clearwing mutation is one of the few that affect different areas of the body selectively.
• The Clearwing Swallowtail, " Cressida cressida ", has been featured twice : 1981 and 1997.
• Both alleles are partially expressed, giving the bird wings like a Greywing and a body colour like a Clearwing.
• Both alleles are partially expressed, giving the bird wings like a Greywing and a body coloured like a Clearwing.
• The Clearwing allele is recessive to the wild-type, dominant to the Dilute allele and co-dominant with the Greywing allele.
• The Greywing allele is recessive to the wild-type, dominant over the Dilute allele and co-dominant with the Clearwing allele.
• The precise origin of the Clearwing mutation is unclear, but Clearwings almost certainly appeared first among Greywing stock in Australia in the late 1920s.
• So the Clearwing mutation exerts a selective effect, not on the wing feathers " per se ", but on cortical pigmentation.
• The Clearwing Light Green has green body feathers only very slightly paler than the normal or wild-type Light Green with highly contrasting yellow wings.
• The Clearwing mutation causes a large reduction in the number of pigment granules in the cortex, but only a very small reduction in the number of pigment granules in the medulla.
• They have a body colour almost as deep as the corresponding normal variety and with the rich sheen of the Clearwing, but with medium grey markings marginally darker than the parent Greywing.
• Other notable moth species that occur on the North Downs include the fiery clearwing moth ( " Bembecia chrysidiformis " ) and straw belle moth ( " Aspitates gilvaria " ).
• When the Clearwing and Greywing alleles are both present the genotype is " dil cw " / " dil gw " and the bird is known as a Full-bodied Greywing.
• The Greywing variety was gradually established during the 1920s in Germany, France, Great Britain and Australia, although in Australia the appearance of the Clearwing mutation in Greywing stock soon afterwards led to the two mutations intermingling.

• There is also a day-flying moth, the thrift clearwing ( " Synansphecia muscaeformis " ); the adult is a bee mimic and the larva feed on thrift ( " Armeria maritima " ).
• The Clearwing is an autosomal mutation of the dil locus given the symbol " dil cw ", and so is a member of the multiple allelic series which also includes the Greywing ( " dil gw " ) mutations.
• When heterozygous with the wild-type allele with the genotype " dil + " / " dil cw " the phenotype is identical to the wild-type Light Green and the bird is known as a split Clearwing.
