By the looks of it from past visits there seems to be a single male (most likely Jabari) that has the majority of the females apart of the harem whilst the other male Azizi, only has some of the younger individuals apart of his harem; which would make sense - especially as most are likely sired by Jabari.
I wonder too, how Melbourne's managing contraception, especially as Juju, Gana and to a stretch, Hudson, will now be potentially reproductive. Obviously the birth of Mei last year, it's proven contraception isn't always reliable. And although these females won't be likely breeding with their father - they'll still be breeding with their uncle.
The export of both Quasi and Mahali to Adelaide made the most sense succession wise. Melbourne now can continue breeding in the future with four lines descending from four lines:
Grace (1996) - Gana (2017)
Huddo (1999) - Juju (2015), Hudson (2018)
Macey (2004) - Makali (2019), Muna (2020), Mei (2021)
Qetesh (2010) - Quilton (2020)
Obviously the plan was to have at least two offspring from each female; and there's a chance Qetesh may be allowed to breed again once some new males arrive, giving the Q line a second breeding female. Of course the birth of Mei in 2021 complicates things as now one of Macey's daughters will probably be exported elsewhere (possibly alongside Macey herself who won't be needed to breed).
