Enzyme variability in the Drosophila willistoni group. IV. Genic variation in natural populations of Drosophila willistoni.
We describe allelic variation at 28 gene loci in natural populations of D. willistoni. Seventy samples were studied from localities extending from Mexico and Florida, through Central America, the West Indies, and tropical South America, down to South Brazil. At least several hundred, and often several thousand, genomes were sampled for each locus. We have discovered a great deal of genetic vari...

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).

متن کاملMaternally Inherited "Sex-Ratio" Conditions in Drosophila Willistoni and Drosophila Paulistorum.
AGNI ( 1952, 1954) and CAVALCANTI and FALCAO ( 1954) have independently discovered strains of Drosophila bifasciata and of Drosophila prosaltans, respectively, which produce progenies consisting mostly or only of females. These abnormalities are transmitted exclusively from mothers to their daughters. Females from the %ex-ratio” strains produce unisexual, or almost unisexual, progenies when cro...
