Fifty lethal-free, sterility-free isogenic lines of Drosophila melanogaster that were randomly sampled from a natural population were tested for net fitness and other components of fitness by competition with D. hydei. Larval viability and developmental time were also measured using the balanced marker method. Distribution patterns of these fitness components were similar, but correlation between the fitness components varied depending on the combinations used. The highest correlations were obtained between net fitness and productivity (r(p) = 0.6987, r(g) = 0.9269). The correlation between net fitness and total larval viability was much lower (r(p) = 0.1473 and r(g) = 0.2171). These results indicate that measuring net fitness, not just a component of fitness, is necessary for the good understanding of the genetic structures of natural populations.
从自然种群中随机抽取的 50 条致死、无菌的同基因系黑腹果蝇被用于与 D. hydei 竞争,以测试净适合度和其他适合度成分。使用平衡标记法还测量了幼虫存活率和发育时间。这些适合度成分的分布模式相似,但不同组合下适合度成分之间的相关性也不同。净适合度和生产力之间获得了最高的相关性(r(p) = 0.6987,r(g) = 0.9269)。净适合度与总幼虫存活率之间的相关性要低得多(r(p) = 0.1473 和 r(g) = 0.2171)。这些结果表明,为了更好地理解自然种群的遗传结构,测量净适合度而不仅仅是适合度的一个组成部分是必要的。
