构巢曲霉的超单倍体和超二倍体菌落，分别为一条或多条染色体的二体性或三体性，表型异常且体细胞不稳定。格拉斯哥菌株已被证明会出现不同的特定表型，具体取决于附加的染色体（Pollard、Käfer 和 Johnston，1968）。该报告扩展了该系统，并表明无论分离株的残留遗传背景如何，表型特异性系统都适用。
Hyperhaploid and hyperdiploid colonies of Aspergillus nidulans, disomic or trisomic for one or more chromosomes respectively, are abnormal in phenotype and somatically unstable. It has been shown for Glasgow strains that a different specific phenotype arises, depending upon which chromosome is additional (Pollard, Käfer & Johnston, 1968). This report extends this system and shows that irrespective of the residual genetic background of the isolate, the system of phenotypic specificity applies.
