Chelewa was born in December 2005(now two and a half) so they must have discovered this by DNA testing more recently.

Viatu was just six when he sired this infant and that is extremely young, though its not unknown for younger males to mate in the presence of a breeding silverback.
'Gorillas Galore' the unofficial studbook lists a different male- Vizuri- as the father of 'Chelewa'. The two males Vizuri and Viatu were born in the same year though Vizuri is 10 months older, and they are possibly more closely related than halfbrothers -they share the same father (Pepe),while their mothers(Quarta & Fadama) are mother and daughter. Pepe is also the father of Quarta's daughter Fadama, so he's Viatu's grandfather as well as his father... so Viatu is very inbred even before fathering a baby by what may be his halfsister. Vizuri has since been sent to Moscow Zoo. I wonder if a DNA test can distinguish between these very closely related two males to tell which is really the father of the baby?
Basel Zoo do have rather a problem with closely related animals in the Gorilla group nowadays. The unrelated silverback 'Kisoro.' who is an elder full brother of Apenheul's 'Jambo, asnd the unrelated female 'Joas' were brought in as outcrosses- however it seems the related animals have been breeding as well. DNA testing would presumably show if Pepe or Kisoro is the father of each of the younger animals and the exact level of inbreeding.
