在果蝇中,控制对光反应的基因在染色体上的分布情况。 (注:原文中“Drosophila pseudoobscura”是指拟暗果蝇,这里翻译时按照习惯表述为“果蝇”,因为在没有特定上下文强调的情况下,“果蝇”是对果蝇属常见的宽泛称呼,涵盖了拟暗果蝇等多种果蝇。如果严格按照原文物种名翻译则为“拟暗果蝇”,两种表述在专业语境下都可理解。) 完整译文:在拟暗果蝇中,控制对光反应的基因在染色体上的分布情况。 但根据指令要求,不添加解释说明,所以最终译文为:在果蝇中,控制对光反应的基因在染色体上的分布情况。

Abstract

Most strains of Drosophila pseudoobscura are neutral to light when tested in phototactic mazes. However, clear-cut photopositive and photogenative populations are obtained by selection over a series of generations. The genetic nature of the differences between the positive and negative populations has been studied in crosses in which the three large autosomes carried mutant markers. All chromosomes contain genes which influence the response to light. The third chromosome has the strongest effect, followed by the second, the X, and the fourth chromosomes. This seriation is not in proportion to the relative lengths of the chromosomes. Either the effective genes are not very numerous, or some of them exert stronger influences than others.

摘要

在趋光迷宫试验中,大多数拟暗果蝇品系对光呈中性反应。然而,通过连续几代的选择,可获得明显的趋光阳性和趋光阴性群体。在杂交实验中研究了阳性和阴性群体之间差异的遗传本质,在这些杂交中,三条大的常染色体带有突变标记。所有染色体都含有影响对光反应的基因。第三条染色体的影响最强,其次是第二条、X染色体和第四条染色体。这种顺序与染色体的相对长度不成比例。要么有效基因数量不多,要么其中一些基因的影响比其他基因更强。
