“…In the current study, one of the parental lines, 2b, was produced by both inbreeding and selecting for low male mating success when males were paired with virgin females (Kaidanov 1980). Males were categorized as having low mating ability if they failed to mate with a virgin female within 30 minutes of introduction.…”

“…Large-effect alleles might have been eliminated because of the strong natural selection operating against them. Indeed, Kaidanov (1980) reports a very high failure rate of lines in his selection experiment due to low mating success and low fertility. In contrast to the results for mating success, two to four significant QTLs were identified for second-male remating success, although the RILs were not as variable for this trait.…”

Abstract. Much of sexual selection theory depends on assumptions about the genetic basis of variation in male mating success and sperm competitive ability. Despite intense interest in this topic, few genes have been identified that contribute to variation in these traits. Here we report the results of quantitative trait locus (QTL) analyses of mating success of male Drosophila melanogaster when exposed to virgin females, remating success of males with previously mated females, and both defense and offense components of sperm competition. We found two to four significant QTLs for remating success, but no QTLs for mating success, even though mating success was more genetically variable than remating success in the recombinant inbred lines used in this study. By combining these results with data from previous gene-expression experiments, we were able to identify three X-linked candidate genes for variation in remating ability. For two of these genes, QTL and expression data were completely concordant with respect to directionality of effects: high mating success was associated with high levels of gene expression and with beneficial QTL effects on the trait. We found equivocal evidence for genetic variation in sperm offense and defense in the recombinant inbred lines, and we did not find any significant QTLs for either sperm competition trait.

Components of mating behavior of Drosophila melanogaster mutant and wild-type strains were studied with respect to fitness. The magnitude of the effect of genotype on the male mating activity, female sexual receptivity, fertility and viability was determined. Strong positive correlation was found between the male mating activity and fitness components. It was shown that mating of strains contrasting in sexual behavior features can be accompanied by both heterosis and maternal effect. Inheritance coefficients were determined for sexual behavior components. GENERAL GENETICS

“…To approach this problem, an experiment was conducted in 1965 in which flies from the Drosophila melanogaster population Yessentuki were selected for low mating activity of males by close inbreeding (Kaidanov, 1980). As a result, a low activity (LA) strain with a complex of morphological, physiological, behavioral, biochemical and genetic alterations, which greatly decreased its fitness, was established (reviewed in: Kaidanov, 1990).…”

“…Also observed was an unusually high rate of spontaneous mutability (Kaidanov, 1980;1990). For example, the frequency of spontaneous lethal mutations in the chromosomes in 2 different generations of selection varied from 2 to 20%.…”

The sources of genetic variability in highly inbred long-term selected strains of Drosophila melanogaster

A highly inbred, long-term selected for low fitness strain LA of Drosophila melanogaster possesses a significant mutational load and unusually high rates of spontaneous mutability as revealed by CyL/Pm method. Our results indicate that during cross of CyL/Pm to LA strains, destabilization of copia-like and mobile elements and induction of H-E hybrid dysgenesis take place. The role of these processes in causing considerable genetic variability of LA strain is discussed.
