Harvey SC, Powell SF, Kennedy DD, McAndrew B & Penman D (2002) Karyotype analysis of Oreochromis mortimeri (Trewavas) and Sarotherodon melanotheron (Ruppell), Aquaculture Research, 33 (5), pp. 339-342.
The karyotypes of both Oreochromis mortimeri (Trewavas) and Sarotherodon melanotheron (Rüppell) are shown to consist of 22 pairs of chromosomes (2n = 44). In O. mortimeri, the karyotype is composed of 9 sm/st and 13 t chromosomes. In the case of S. melanotheron, the karyotype is composed of 15 sm/st, 2 m and 5 t chromosomes. The karyotypes of these species are therefore similar to those of the majority of other tilapia species, with that of S. melanotheron being considerably different from that previously reported for this species.
