1. Color and wing size: identifying targets of sexual selection in Drosophila melanogaster
Kandidat-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)Sammanfattning : This study explores the relationship between wing size, coloration, and reproductivesuccess in Drosophila melanogaster, fruit flies. Sexual selection, a key aspect ofevolutionary biology, often involves visual signaling as a means of displaying geneticinformation. LÄS MER
2. Varför är den relativa fitnessen högre för hanar av Drosophila melanogaster som bär allel A2 jämfört med allel A1 på genen CG3598? : Experimentell studie på bakomliggande faktorer till skillnad i fitness hos hanar med olika allel varianter på gen CG3598
Kandidat-uppsats, Karlstads universitet/Avdelningen för biologiSammanfattning : Sexual conflict is a term that describes the situation where traits can experience opposing selection pressures in the two sexes. Theory suggests this conflict exists in all organisms with separate sexes, and specific chromosome clusters which are possibly sexually antagonistic have been identified in the species Drosophila melanogaster.

3. Fekunditet hos honor av Drosophila melanogaster med en potentiell sexuellt antagonistisk gen : En fördjupande studie inom experimentell validering av en potentiell sexuellt antagonistisk gen hos Drosophila melanogaster
Kandidat-uppsats, Karlstads universitet/Institutionen för miljö- och livsvetenskaper (from 2013)Sammanfattning : Sexual conflicts arise when there is a difference in how females and males of a species or population achieve their maximum reproductive fitness. In intralocus sexual conflicts, alleles at a given locus are exposed to conflicting, or antagonistic, selection pressures. LÄS MER
4. Statistical Analysis and Modeling of the Behavioral Response to Humidity and Olfactory Cues by the Vinegar Fly Drosophila melanogaster
Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknikSammanfattning : Animals are impacted by the humidity of their surrounding environment, it affects their ability of thermoregulation, water retention and their overall well-being. For small insects the effects of the surrounding humidity is even more important as they have a limited water storage which depletes faster in a drier environment. LÄS MER
5. The role of odor receptor protein Or22a in Drosophila melanogaster oviposition and the response spectra of chimeric receptor protein Or22a-b
Kandidat-uppsats, Lunds universitet/Examensarbeten i molekylärbiologiSammanfattning : The fruit fly Drosophila melanogaster has a well-studied olfactory system. A crucial part of the olfactory system is the olfactory sensory neurons (OSNs). One type of these OSNs, Ab3a, expresses the Odor receptors (ORs) Or22a and Or22b. LÄS MER
