I think Port Lympne probably choose the rhinos they send for relocation on an 'age suitability' basis as much as anything. But most of their younger rhinos are sired by the same two or three bulls so there are plenty of relatives of the relocated rhinos still living at Port Lympne.
I do know with the Gorillas though at least one baby that was returned to Africa was the(then)only offspring of a wildcaught female(Sidonie) and I don't think she's had any more since(?). So her genes are unlikely to be represented in the captive population in future.
