Tests for reproductive isolation between lines selected for locomotor activity were performed. Three sets of selection lines were used, each consisting of lines selected for low and high locomotor activity from the same base population. Females preferred high-activity males in almost every case. However, in one of the sets temporary sexual isolation was found between flies of the high and low lines. This was accompanied in the low-activity females with a higher fertility when they were mated… 

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.

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.

An Experiment Testing Two Hypotheses of Speciation

The results of this experiment and previous, related ones support the view that either genetic drift or selection is by itself sufficient to produce reproductive isolation as a pleiotropic by-product and help establish sexual isolation in Drosophila simulans.

DIVERGENT AMBULATORY AND GROOMING BEHAVIOR IN SERIALLY BOTTLENECKED LINES OF THE HOUSEFLY

The extent of genome‐wide restructuring predicted in bottleneck models of speciation is addressed in assays of non‐reproductive behavior in lines of the housefly, suggesting increased evolutionary potential for ritualization due to bottlenecks.

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 Preferences Are Not Predictive of the Direction of Evolution in Experimental Populations of Drosophila

In mate preference tests with strains of Drosophila melanogaster whose ancestral and derived relationships were known, no correspondence was found between sexual isolation and direction of evolution.

SERIALLY BOTTLENECKED LINES OF THE HOUSEFLY

This study documents nondebilitating differentiation in the courtship repertoire that can account for divergent mating propensities and premating isolation in houseflies.

Investigating the interaction between inter-locus and intra-locus sexual conflict using hemiclonal analysis in Drosophila melanogaster

The results indicate a statistically non-significant trend suggesting that increasing the strength of IeSC ameliorates IaSC in the population, and there is growing support for the idea that the two may interact.

Laboratory environments are not conducive for allopatric speciation

It is suggested that allopatric speciation experiments are more likely to yield conclusive results under divergent selection than under drift, and points to the benefits of large populations and many generations.

A STUDY OF SEXUAL ISOLATION BETWEEN CERTAIN STRAINS OF DROSOPHILA PAULISTORUM

It appears to be a general rule that where two or more of the incipient species are sympatric in the same territory, no hybrids between them are formed spontaneously, and crosses can be made in laboratory experiments only with considerable difficulty, always yielding sterile hybrids.

The effects of inbreeding and artificial selection on reproductive fitness

The response of an equilibrium population of a cross-fertilized species to artificial selection for extreme expression of a chosen quantitative character is a phenomenon which is as yet only very imperfectly understood, and it is not clear what part the changes in fitness will play in determining the ultimate limits to selection.

A slight, but statistically quite significalit, sexuial isolation has arisen as a by-product of selection for geoand phototaxis in Drosophila melanogaster.

REVERSIBILITY IN EVOLUTION CONSIDERED FROM THE STANDPOINT OF GENETICS 1

It is inferred that evolution proceeded contrary to the prevailing mutation pressure, and hence only by the aid of selection, and a certain reverse evolution would tend to occur, so far as individual loci were concerned.
