Matings between Drosophila pseudoobscura strains differing at the amylase (Amy) locus were observed in Elens-Wattiaux chambers. Males homozygous for either Amy1.00 or Amy0.84 alleles in the CH gene arrangement enjoyed a mating advantage when moderately rare, but none when quite rare. The minority male advantage for strains differing at the Amy locus, and other loci linked to it, was comparable in size to that observed between strains carrying the ST or CH gene arrangements, and either alike or different at the Amy locus. Although some features of our results are puzzling, there is evidence that the Amy locus and others for which it serves as a marker have effects on mating behavior which include some degree of rare male mating advantage.
在埃伦斯 - 瓦蒂奥克斯培养箱中观察了在淀粉酶（Amy）位点存在差异的拟暗果蝇品系之间的交配情况。在CH基因排列中，对于Amy1.00或Amy0.84等位基因纯合的雄性果蝇，在适度稀少时具有交配优势，但在非常稀少时则没有。在Amy位点及与之连锁的其他位点存在差异的品系中，少数雄性优势的大小与携带ST或CH基因排列、在Amy位点相同或不同的品系之间观察到的相当。尽管我们结果的某些特征令人困惑，但有证据表明，Amy位点以及它作为标记的其他位点对交配行为有影响，其中包括某种程度的稀有雄性交配优势。
