Based on the DMR test, 18 members of the nasuta-albomicans complex of Drosophila are constructed into clusters and named in the hierarchical form from the lowest to the highest mean lifetime fecundity (Fig. 5a), ovariole number (Fig. 5b) and lifetime fertility (Fig. 5c). The members belonging to each cluster have insignificant differences. For life time fecundity, six clusters were recognized, of which, cluster 1 to 5 are overlapped with each other, while cluster 6 (C8) is formed as independent cluster. For ovariole number, six clusters were recognised, of which, except cluster 1 (N), all the other clusters from 2 to 6 are overlapped, while cluster 1 is formed as independent cluster. For fertility, cluster 1 (C13) is formed as independent cluster, while cluster 2 to cluster 7 are overlapped with each other.
