Abstract
Artificial selection has produced populations of Drosophila melanogaster which show either positive or negative phototactic behavior. Selection was carried out in the presence of various marked multiple inversions used to suppress genetic recombination. Reciprocal hybridizations between photopositive and photonegative populations of flies have revealed the X chromosome of D. melanogaster to be important in phototactic behavior regardless of conditions which restricted genetic recombination during selection.
摘要
人工选择培育出了具有正趋光行为或负趋光行为的黑腹果蝇种群。选择过程是在存在多种用于抑制基因重组的标记多重倒位的情况下进行的。正向趋光和负向趋光果蝇种群之间的正反交杂交表明，无论在选择过程中限制基因重组的条件如何，黑腹果蝇的X染色体在趋光行为中都很重要。
