在两个种群的果蝇，双向选择和单对交配的高和低表达的中央兴奋状态（CES）成功地产生一个高，但不是一个低，CES线，从另一个低，但不是一个高，CES线。与已发现的一个与CES相关的主效基因的选择性研究结果相比，本研究结果表明，在果蝇中，与CES相关的主效基因是一对，而与CES相关的主效基因是一对。在黑腹果蝇中，CES有几个相关基因，其中一些的相对等位基因在分歧系中已经固定。
In two populations of Drosophila melanogaster, bidirectional selection and single-pair matings for high and low expression of central excitatory state (CES) succeeded in producing from one a high, but not a low, CES line, and from the other a low, but not a high, CES line. Compared with results from the selection studies of the blow fly, Phormia regina, in which one major gene correlate of CES has been found, the results from this study suggest that in D. melanogaster there are several gene correlates of CES, opposite alleles of some of which have become fixed in the divergent lines.
