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...
متن کاملCHROMOSOMAL POLYMORPHISM IN DROSOPHILA EURONOTUSl
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 کاملDivergence between the Drosophila pseudoobscura and D. persimilis genome sequences in relation to chromosomal inversions.
As whole-genome sequence assemblies accumulate, a challenge is to determine how these can be used to address fundamental evolutionary questions, such as inferring the process of speciation. Here, we use the sequence assemblies of Drosophila pseudoobscura and D. persimilis to test hypotheses regarding divergence with gene flow. We observe low differentiation between the two genome sequences in p...
