The Variability of Ocellar Bristles and Their Inheritance in Drosophila melanogaster Meigen
Abstract
Geographic separation of populations is often followed by an accumulation of several small genetic differences. Dobzhansky and queal (1938) and Dobzhansky and Sturtevant (1938) have shown in studies involving ten populations of Drosophila pseudoobscura Frolova, which were collected from different localities in vestern United States, that not only a conspicuous frequency of concealed genetic variations oc- curred, but also the individual populations were frequently dissimilar with respect to the gene arrangement on their chromosomes. Certain features of the discontinuous distri- bution of gene arrangements and their replacement by other linear orders were ascribed to variances in ecological fit- ness and selective values.
