A mutation which changes courtship song in Drosophila melanogaster
Behavior Genetics
|May 1, 1977
Summary
Researchers identified a mutant fruit fly (Drosophila melanogaster) with altered courtship songs, specifically longer pulse intervals and durations. This genetic mutation affects the fly
Area of Science:
- Behavioral genetics
- Animal communication
- Drosophila melanogaster research
Background:
- Courtship song is crucial for Drosophila melanogaster mating success.
- Understanding song variations can reveal genetic underpinnings of behavior.
Purpose of the Study:
- To isolate and characterize a mutation affecting Drosophila melanogaster courtship song.
- To map the genetic locus and fate-map the mutation responsible for aberrant song.
Main Methods:
- Isolation of a mutant Drosophila melanogaster exhibiting altered courtship song.
- Analysis of song parameters: pulse interval, pulse length, and pulse polycyclicity.
- Genetic mapping and fate-mapping techniques were employed.
Main Results:
- The mutant displayed increased pulse intervals and pulse lengths.
- Courtship song pulses were polycyclic, unlike the wild-type monocyclic pulses.
- Flight wingbeat and sine song frequency remained unaffected.
- Genetic mapping was successful, but fate-mapping yielded inconclusive results.
Conclusions:
- A specific mutation in Drosophila melanogaster significantly alters courtship song structure.
- The mutation's effects are specific to song pulse characteristics, not flight mechanics.
- Further investigation is needed to resolve the mutation's precise developmental origins.

02:32Position-effect Variegation
In 1928, a German botanist Emil Heitz observed the moss nuclei with a DNA binding dye. He observed that while some chromatin regions decondense and spread out in the interphase nucleus, others do not. He termed them euchromatin and heterochromatin, respectively. He proposed that the heterochromatin regions reflect a functionally inactive state of the genome. It was later confirmed that heterochromatin is transcriptionally repressed, and euchromatin is transcriptionally active chromatin.
02:27Background and Environment Affect Phenotype
Although the genetic makeup of an organism plays a major role in determining the phenotype, there are also several environmental factors, such as temperature, oxygen availability, presence of mutagens, that can alter an organism’s phenotype.
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...

02:45The Ratio of X Chromosome to Autosomes
In most organisms, sex is determined by the ratio of X and Y chromosomes. However, in some organisms, such as Drosophila and C.elegans, sex is determined by the ratio of the number of X chromosomes to the number of sets of autosomes. The Y chromosome in Drosophila is active but does not determine sex. It contains genes responsible for the production of sperms in adult flies.
Normal male Drosophila has a ratio of one X chromosome to two sets of autosomes. In contrast, normal female Drosophila...
