    Area of Science:

    • Biochemistry
    • Population Genetics
    • Molecular Biology

    Background:

    • Enzyme polymorphisms are crucial for understanding genetic variation within populations.
    • The alcohol dehydrogenase (Adh) locus in Drosophila melanogaster is a well-studied model for enzyme polymorphism.

    Purpose of the Study:

    • To investigate the maintenance of genetic variation at the Adh locus in Drosophila melanogaster using a biochemical approach.
    • To correlate biochemical findings with the results of competition experiments.

    Main Methods:

    • Utilized biochemical techniques to analyze enzyme variation.
    • Conducted competition experiments to assess the fitness of different Adh genotypes.

    Main Results:

    • Established a direct correlation between biochemical data and the outcomes of competition experiments.
