Variance component analysis of allozyme frequency data from eastern populations of Drosophila melanogaster.
Gene frequency variation at eight polymorphic allozyme loci in Drosophila melanogaster populations in North Carollina and the east coast of the United States were analyzed utilizing the variance component estimation procedures suggested by Cockerham (1969, 1973). These variance components were used to estimate correlations of genes within small geographic regions. The average (over loci) correl...

اندیشمندان و صاحب نظران علوم اجتماعی بر این باورند که مرحله تازه ای در تاریخ جوامع بشری اغاز شده است. ویژگیهای این جامعه نو را می توان پدیده هایی از جمله اقتصاد اطلاعاتی جهانی ، هندسه متغیر شبکه ای، فرهنگ مجاز واقعی ، توسعه حیرت انگیز فناوری های دیجیتال، خدمات پیوسته و نیز فشردگی زمان و مکان برشمرد. از سوی دیگر قدرت به عنوان موضوع اصلی علم سیاست جایگاه مهمی در روابط انسانی دارد، قدرت و بازتولید...
15 صفحه اولSleep in populations of Drosophila melanogaster Sleep in populations of Drosophila melanogaster
15 The fruit fly Drosophila melanogaster is a diurnal insect active during the day with 16 consolidated sleep at night. Social interactions between pairs of flies have been shown to 17 affect locomotor activity patterns, but effects on locomotion and sleep patterns have not been 18 assessed for larger populations. Here, we use a commercially available Locomotor Activity 19 Monitor (LAM25H) syst...
متن کاملGenetic and molecular analysis of smooth, a quantitative trait locus affecting bristle number in Drosophila melanogaster.
A semi-lethal, sterile allele of the smooth locus (2-91.5), sm3, was discovered in an artificial selection line for low abdominal bristle number that had been started from a P-M dysgenic cross. The fitness effects and extremely low bristle number phenotype of the allele could not be separated by recombination from a P-element insertion at cytological location 56E, and precise excision of the P-...
متن کاملAn Analysis of the Bristle Forming Reactions in Drosophila Melanogaster Scute-1.
( I ~ I ) , PLUNKETT (1926), STANLEY (1932), and HARNLY (1932, 1936). Some of these workers have attempted to explain the mechanism of the temperature effect by the form of the curves obtained when the values of the measured character are plotted against the time of transfer. It is significant that the form of these curves, in all cases, appears to be sigmoid, resembling to some extent the prob...
