Reversion from Roughest to Wild Type in Drosophila Melanogaster.
OUGHEST is a sex-linked, recessive character of Drosophila melanoR gaster manifested phenotypically in bulging, roughened eyes that have facets irregular in size and shape. The allele roughest3 (mi3) was obtained by GRUNEBERG (1935) from an X-ray experiment. Eyes of rst3 flies show mosaics of smooth and rough facets with rough patches more pronounced in the males than in the females. Roughness ...
متن کاملSomatic reversion of chromosomal position effects in Drosophila melanogaster.
A transgene was inserted at several different chromosomal sites in Drosophila melanogaster, where its expression was subject to genomic position effects. Quantitative position effects and variegated and constant patterned position effects were observed. We investigated the status of the affected gene in the somatic cells where it normally functions. The FLP site-specific recombinase was used to...
متن کاملmanipulation in dubbing and subtitling
پژوهش حاضر در چارچوب مکتب دستکاری قرار گرفت و با استفاده از تقسیم بندی دوکات (2007) از شیوه های دستکاری، به دنبال یافتن پاسخ برای پرسش های زیر بود: 1-رایج ترین شیوه دستکاری در دوبله فیلم ها کدام است؟ 2-رایج ترین شیوه دستکاری در زیرنویس فیلم ها کدام است؟ 3-دستکاری در دوبله فیلم ها رایج تر است یا در زیرنویس آن ها؟ این پژوهش از نوع تحقیقات توصیفی- مقایسه ای و پیکره ای می باشد. پیکره تحقیق شا...
Spontaneous reversion of the white-ivory mutant of Drosophila melanogaster.
EVERAL studies have shown that certain mutants revert more frequently when homozygous than when hemizygous, a phenomenon termed “selfing” by DEMEREC (1 962). Reversion of serial tandem duplications by asymmetric pairing and crossing over has been demonstrated for several mutants following the classical study of Bar by STURTEVANT (1925). For Salmonella typhimurium, DEMEREC (1 962, 1963) has repo...
متن کاملRepression of P element-mediated hybrid dysgenesis in Drosophila melanogaster.
Inbred lines derived from a strain called Sexi were analyzed for their abilities to repress P element-mediated gonadal dysgenesis. One line had high repression ability, four had intermediate ability and two had very low ability. The four intermediate lines also exhibited considerable within-line variation for this trait; furthermore, in at least two cases, this variation could not be attributed...
