Selection for high and low locomotor activity has been applied in two base populations ofDrosophila melanogaster of distinct geographical origin. From each base population a high and a low line were selected, in which anesthesia was performed with ether. In addition, from one of the base populations a high line and a low line were selected under CO2 narcosis. Locomotor activity was measured in an apparatus consisting of rows of 20 tubes in a line. Heritabilitities in the base populations… 

Divergent selection on locomotor activity inDrosophila melanogaster. II. Test for reproductive isolation between selected lines

Females preferred high-activity males in almost every case and temporary sexual isolation was found between flies of the high and low lines in one of the sets of selection lines.

Divergent selection on locomotor activity inDrosophila melanogaster. III. Genetic analysis

Reciprocal crosses between the high and low lines of one of these pairs showed that a considerable part of the activity differences was contributed by differences between the X chromosomes, and low-activity alleles tended to be dominant over alleles for high activity.

Asymmetric response to directional selection for licking behavior ofDrosophila melanogaster males

The selection for licking in males had no discernible effect on female sexual activity and was carried out on courting males of a cage-population of Drosophila melanogaster.

Genetic analysis of fickle locomotor behaviour inDrosophila melanogaster

The results suggest the presence of some major genes influencing fickle locomotion in both sexes on chromosome 3.

Investigating whether a highly dimorphic trait—adult locomotory activity—contributed substantially to the established intralocus sexual conflict in the LHM laboratory-adapted population of Drosophila melanogaster found significant phenotypic variation in both sexes for adult locomOTory activity, and that the selection gradients on this variation were large and in opposite directions in the two sexes.

Genetic analysis of adult locomotor activity in Drosophila melanogaster

The results suggest the presence of several genes influencing locomotor activity on both chromosomes analyzed in Drosophila melanogaster.

A genetic analysis of locomotor activity in Drosophila melanogaster

Variation in the locomotor activity of females has little effect on the amount of wing vibration which males direct at them, but significantly affects the amountof contact stimulation by licking which they receive.

Mating speed and the interplay between female and male courtship responses inDrosophila melanogaster (Diptera: Drosophilidae)

Estimates of general activity and sexual behavior for various genotypes within a strain of Drosophila melanogaster, which had known differences in mating speed, and an analysis of the interplay between female and male courtship behaviors enabled the examination of signal-response differences between the inbred lines.




The design and construction of two multiple Y-unit mazes are described which will permit time assessment of the mean and variance of phototactic behavior in Drosophila populations, and an analysis of the behavior of the selected and unselected strains shows the interaction of the environmental and genetic influences.

There was a tendency for both activity and preening to decrease in response to shadow stimulation, which indicates that this form of reaction is advantageous and suggests a relation to the avoidance of predation.

Selection for geotaxis inDrosophila melanogaster: Heritability, degree of dominance and correlated responses to selection

The frequencies of polymorphic inversions declined in every population during selection, but the population under neutral selection seemed to maintain a higher chromosomal polymorphism than those under positive or negative selection.

A genetic analysis of phototactic behavior in Drosophila melanogaster I. Selection in the presence of inversions.

The effectiveness of selection for positive and negative phototactic behavior in populations of Drosophila melanogaster heterozygous for various multiple inversions was compared using the method of realized heritability and the results are discussed in terms of the organization of genes influencing phototact behavior in this species.

Disruptive and Stabilizing Selection on the "Escape" Behavior of DROSOPHILA MELANOGASTER.

It is proposed that reproductive isolation may be evolved under appropriate conditions of disruptive selection, which may eventually result in a polymorphism, or possibly, a “disruption” of the common gene pool.

Effects of selection and migration on geotactic and phototactic behaviour of Drosophila. II

It is shown that the result is explicable when the characteristics concerned have very low heritabilities, and that the migrants came from genetically improving populations, meaning by ‘improvement’ simply that these populations were changing in the direction for which they were being selected.

Heritability of Phototactic and Geotactic Responses in Drosophila pseudoobscura

Estimation of the heritability through parent-offspring correlation in an unselected base population after one generation of assortative mating will avoid most of the problems encountered in the estimation of realized heritability.
