Apparently about 20 years ago an impure giraffe was bred with pure bred Rothschild's, thus contaminating the gene pool.
However I was told that the person who made this discovery based his dientification on a photograph of the animal in question. Chester Zoo refer to them as Rothschild's Giraffes.
Can we rewind a bit here... This news indicates that crossing occurred in a captive group somewhere a long time ago. Is the suggestion that MANY(even all) Rothschild's giraffe in UK originate from this source so they could also be suspect? So this applies not only to the ones at Chester?
And do you know where CHester's came from ?
