Variation of two wing morphology characters was studied in 11 X-chromosome substitution lines and three outbred lines of D. melanogaster, as a test of quantitative genetic predictions regarding variance components and heritabilities. As expected from inbreeding of the lines, between-lines components of phenotypic variance are statistically significant, while the significant within-line component is attributable to a maternal effect. Unusually low broad-sense heritabilities were observed in the inbred lines, and unusually low narrow-sense heritabilities were observed in the outbred lines. Low heritability estimates cannot be explained by insensitive measurement techniques, since the techniques were sufficiently sensitive to detect significant maternal effects. The most likely explanation for the low heritability estimates is the operation of natural selection on wing or correlated characters as stocks adapt to the laboratory environment.
在11个X染色体代换系和3个黑腹果蝇远交系中研究了两个翅形态特征的变异，以此作为关于方差成分和遗传力的数量遗传学预测的一项检验。正如从这些品系的近亲繁殖所预期的那样，表型方差的品系间成分具有统计学显著性，而品系内的显著成分则归因于母体效应。在近交系中观察到异常低的广义遗传力，在远交系中观察到异常低的狭义遗传力。低遗传力估计值不能用不灵敏的测量技术来解释，因为这些技术足够灵敏以检测到显著的母体效应。低遗传力估计值最可能的解释是，随着品系适应实验室环境，自然选择作用于翅或相关性状。
