Budi`s genes are also well-represented from Ramon`s side - Ramon has 3 living daughters (Dina, Yasmin, Indra - all 3 breeding with more calves to come in the future), and 2 sons, one who is already breeding with 2 living calves and likely 2 more on the way (Timber) and one (Max) who will most likely breed in the future. Ramon`s genes are not yet over-represented, but well-enough-represented so that Budi is not a loss for the EEP genetically.
You are right that there are pretty much no over-represented bulls in the asian elephant EEP yet - in my opinion not even the Emmen calves, because a) they are from 6 different wildborn females, and that the bulls (Radza or Naing Thein) have a lot more offspring, doesn`t mean the calves aren`t important from their mother`s side, and b) there is not a lot of breeding in the second generation from Emmen born elephants yet, like with the Hannover calves. I think Ananda - who was originally scheduled to go to the US too - is actually more important for the EEP then Budi, because none of his siblings from either his fathers nor his mothers side has yet bred. Gandhi from Kopenhagen (now Heidelberg) would have been a pretty good candidate too, with 2 siblings (Irma and Chang) with a lot of offspring, but he may have some health problems (unexplained pain in his hind legs) that would make him a bad candidate to travel overseas. All in all, I`m happy that only one bull left...
