Experiments have been performed to study the effect of selection at the Odh locus in Drosophila melanogaster populations using different alcohol concentrations in the medium. The data can be best interpreted by assuming frequency-dependent selection. When genotype frequencies are considered as independent variables and values of Wrightian fitness as dependent variables, it turns out that different functions describe the selection of the coexisting genotypes. A linear equation is used for the SF genotype and a hyperbolic function for the FF genotype. No function of good fit could be found for the SS genotype. Simulation experiments using these functions fit our data well.
已进行实验以研究在培养基中使用不同酒精浓度时，黑腹果蝇群体中Odh基因座的选择效应。通过假设频率依赖选择可以最好地解释这些数据。当将基因型频率视为自变量，而赖特适应性值视为因变量时，结果发现不同的函数描述了共存基因型的选择。对于SF基因型使用线性方程，对于FF基因型使用双曲线函数。未找到适用于SS基因型的拟合良好的函数。使用这些函数的模拟实验很好地拟合了我们的数据。
