  1. 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)

    Författare :Ellen Pääjärvi Våg; [2024]
    Nyckelord :Sexual selection; wing interference patterns; Drosophila melanogaster; visual signaling; sexuell selektion; vingmönster; bananfluga; visuell signalering;

    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. 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 biologi

    Författare :Joel Kilhage; [2023]
    Nyckelord :Genetics; Genetic; P1; P2; Drosophilla melanogaster; Evolution; Fitness; Sperm defense; Sperm offense; A1; A2; Genetik; Drosophilla melanogaster; Bananfluga; Bananflugor; Evolution; A1; A2; Fitness; Relativ fitness; Gen; P1; P2; Spermie anfall; Spermie försvar;

    Sammanfattning : 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. 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)

    Författare :Sara Lindh; [2022]
    Nyckelord :sexual antagonism; sexual conflicts; fruitflies; drosophila melanogaster; drosophila; GWAS; antagonistic sexual selection; fecundity; intralocus sexual conflict; reproductive fitness; sexuell konflikt; sexuella konflikter; drosophila melanogaster; drosophila; bananflugor; sexuell antagonism; fekunditet;

    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. 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 teknik

    Författare :Jonathan Lind; [2021]
    Nyckelord :Technology and Engineering;

    Sammanfattning : 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. 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 molekylärbiologi

    Författare :Lovisa Pettersson; [2018]
    Nyckelord :Biology and Life Sciences;

    Sammanfattning : 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
