Pigmentation in a Mottled White Eye Due to Position Effect in Drosophila Melanogaster.
HE phenomenon of phenotypic variegation in Drosophila, due to the T translocation of a gene in a euchromatic region of the chromosomes to the neighborhood of a heterochromatic one, has been studied widely and interpreted in various ways (see BELGOVSKY 1946; EPHRUSSI and SUTTON 1946). After an analysis of one example of this variegation, the mottled white eye of the stock T ( 1 ; 4)7P8-18 of D. ...
متن کاملParental control of position-effect variegation. II. Effect of sex of parent contributing white-mottled rearrangement in Drosophila melanogaster.
HE extensive phenotypic variation among individuals exhibiting positionTeff ect variegation has long hampered investigations of the mechanism of position effect. The variegated phenotype itself is associated with loci near the breakage points of chromosomal rearrangements. The genes subject to position effect are not mutant in the strict sense, at least in the germ line, since they can be recov...
متن کاملThe Effect of Temperature on a Mottled-Eye Stock of Drosophila Melanogaster.
The following paper presents data on the effect of temperature on a mottled-eyed fly, a mutation appearing in a progeny of flies which had been subjected to supersonic radiations in an experiment carried out by HERSH, KARRER and LOOMIS (1930). The original stock was slightly changed by the insertion of sex-linked vermilion by W. P. SPENCER of THE COLLEGE OF WOOSTER. Such was the status of the s...
متن کاملCharacterization of enhancer-of-white-apricot in Drosophila melanogaster.
The white-apricot (wa) allele differs from the wild-type white gene by the presence of the retrovirus-like transposable element copia within the transcription unit. Most RNAs derived from wa have 3' termini within this insertion, and only small amounts of structurally normal RNA are produced. The activity of wa is reduced in trans by a semidominant mutation in the gene Enhancer-of-white-apricot...
متن کاملToxicological Evaluation of a New Lepidopteran Insecticide, Flubendiamide, in Non-Target Drosophila melanogaster Meigen (Diptera: Drosophilidae)
Background: Flubendiamide, comparatively a new pesticide designed to eradicate lepidopteran insect pests is known to have low risk to birds, mammals, fish, algae, honey bees, non-target arthropods, earthworms, soil macro- and micro-organisms, non-target plants as well as sewage treatment organisms; however, the risk assessment for aquatic invertebrates from metabolite could not be finalized wit...
