拉尔丹D.将黑腹果蝇暴露于亚致死温度。诱导的最常见的形态变化是模拟已知突变的体细胞效应。这些效应，指定的表型拷贝，是相当具体的特定处理，并容易重现。然而，它们随着果蝇被处理的阶段、温度而变化。它们所暴露的环境、治疗的持续时间以及被治疗个体的遗传构成。不同性状处理的有效期不同。研究得最广泛的类型是kn-effect[长破折号]，一种可变程度的机翼缩减。产生这种效应的敏感期为41/2-6天，最适期为51/4天。它几乎只发生在暴露于35[degree]C之后。12-24小时。确定了三种特定的遗传修饰剂;其他几种可能存在。检查的各种股票的有效性的顺序是[长破折号]无脊椎，俄勒冈州，酒吧，佛罗里达，白色。结果解释在作者的“生理理论”，涉及各种发展过程的反应速率的定量变化。参数，以排除平行诱导和发展反应的质的变化。|| 摘要：M.

Larvae of D. melanogaster were exposed to sub-lethal temps. The most frequent morphological changes induced were somatic effects simulating known mutations. These effects, designated pheno-copies, were fairly specific for particular treatments and were readily reproducible. They varied, however, with the stage at which the flies were treated, temp. to which they were exposed, duration of the treatment, and genetic constitution of the treated individuals. The period during which treatment was effective was different for different characters. The type most extensively studied was the kn-effect[long dash]a wing reduction of variable degree. The sensitive period for the production of this effect was 41/2-6 days of development with the opt. at 51/4 days. It occurred almost exclusively after exposure to 35[degree]C. for 12-24 hrs. Three specific genetic modifiers were identified; several others were probably present. The order of effectiveness of various stocks examined was[long dash]spineless, Oregon, bar, Florida, white. The results are interpreted in terms of the author's "physiological theory" involving quantitative changes in reaction rates of various developmental processes. Arguments are presented to exclude parallel induction and qualitative changes in developmental reactions. || ABSTRACT AUTHORS: M. D. Schweitzer
