为了探讨潜在的反应自然选择的反应规范的年龄和大小在成熟时,羽化时的鲜体重大量选择丰富和贫穷的幼虫食物条件下的果蝇。羽化时的干重的敏感性,丰富和贫穷的幼虫食物之间的差异选择使用家庭之间的敏感性差异。对于这两个实验,相关的响应选择羽化年龄进行了检查。这些果蝇来自野生种群,在实验开始前已经在实验室大量培养了六个多月。这些苍蝇响应选择体重向上和向下丰富和贫穷的幼虫食物。在至少一个方向上,增加或降低体重敏感性的选择也是成功的。敏感性降低选择向上在一个贫穷的环境和向下在一个丰富的环境。
To investigate the potential response to natural selection of reaction norms for age and size at maturity, fresh body weight at eclosion was mass selected under rich and poor larval food conditions in Drosophila melanogaster. The sensitivity of dry weight at eclosion to the difference between rich and poor larval food was selected using differences in sensitivities among families. For both experiments, the correlated response to selection of age at eclosion was examined. The flies were derived from wild populations and had been mass cultured in the lab for more than six months before the experiments started. These flies responded to selection on body weight upwards and downwards on both rich and poor larval food. Selection on increased or decreased sensitivity of body weight was also successful in at least one direction. Sensitivity was reduced by selection upwards in a poor environment and downwards in a rich environment.
