Chromosomal Adaptive Polymorphism in Drosophila Persimilis. I. Life Cycle Components under near Optimal Conditions.
T least three principal facts concerning the adaptive functions of chromosomal A variants (inversions) in Drosophila populations have been established notably by DOBZHANSKY (1947, 1955), DOBZHANSKY and WALLACE (1953), DOBZHANSKY and LEVENE (1951), DOBZHANSKY and PAVLOVSKY (1953), and WALLACE (1953) : 1) Natural selection may build up particular genic complexes in a chromosomal variant adapting ...
متن کاملGene Polymorphism in Natural Populations of DROSOPHILA PERSIMILIS.
Genetic variation at 43 loci has been studied in six different populations of Drosophila persimilis by electrophoresis of enzymes and proteins. In D. persimilis the mean proportion of polymorphic loci is 0.362, the mean proportion of heterozygous loci per individual is 0.100 and the average number of alleles per locus is 1.651. In all populations, the loci coding for the hydrolytic and other no...

TUDY of the naturally occurring polymorphism found in the banded polytene Schromosomes of Diptera has yielded a great deal of information on the genetic structure of natu -a1 populations, and also in some instances has indicated the pattern of evolut .onary change which has occurred during species formation. Outstanding examples of studies of the latter sort are those in the Drosophila obscura ...
متن کاملChromosomal Polymorphism in Drosophila Rubida
HE population geneticist is essentially interested in the variation of gene freTquencies in natural populations. Within chromosomal inversions blocks of genes are contained and in many species of Drosophila due to the presence of easily analysable giant chromosomes, the behavior of these blocks of genes can be easily studied in natural populations. Thus, of recent years chromosomal inversion po...
متن کاملChromosomal control of mating activity in Drosophila pseudoobscura.
Lines containing two third-chromosome inversions (Arrowhead and Pikes Peak) of Drosophila pseudoobscura selected for fast and slow mating speed were crossed to a multichromosomal, dominant marker inversion stock, and strains with various combinations of chromosomal derivation were tested for their mating activity. When lines were selected isodirectionally with the known third-chromosome control...
