متن کاملThe Linkage of Eight Sex-Linked Characters in DROSOPHILA VIRILIS.
The present paper deals with eight sex-linked mutant characters that have arisen in my cultures of Drosophila virilis Sturtevant.l The eight characters are as follows: Yellow, body color. Magenta, eye color. Glazed, eye surface (figure 5). Forked, bristles on the thorax (figure 2). Vesiculated, wings. Rugose, eye surface (figure 4). Frayed, bands on the abdomen (figures 3 and 6). Hairy, eye sur...
متن کاملPositive and negative geotaxis: sex-linked traits in Drosophila pseudoobscura.
Using a Hirsch classification maze, selection was made for positive and negative geotactic behaviors in three different strains of Drosophila pseudoobscura. Hybridization studies were then carried out with flies from the diverged strains. The geotactic scores of the parents and F1 flies indicate that both negative and positive geotactic behaviors in these strains are strongly influenced by gene...
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...
متن کاملSex-linked auxotrophic and putative auxotrophic mutants of Drosophila melanogaster.
Thirty-two mutants with improved growth response on a yeast-sucrose compared with a defined medium have been characterized with respect to ribonucleoside supplementability. Twenty mutants respond to either pyrimidine ribonucleoside. Four mutants respond to one or both purine ribonucleosides. Eight mutants ("putative" auxotrophs) do not respond to dietary RNA supplementation. Mapping and complem...
