@sanjay, can you fix this please?

yea not surprised..been thinking that kazi tigers are pretty inbred for a while now what's interesting is for ranthambore tigers also being inbred not a single tabby or white tiger has been recorded yet @Ashutosh

Probably the greengrocers trait doesn't exist in that population... It is not directly related to inbreeding, but the rate of explosion.

During its worst days Kaziranga had less than 50 tigers what it became a TR in 1972, in following years all tigers from nearby forests moved into Kaziranga & stayed due to its quality. There were 80 in by turn of millennium & adjoining forests became abandoned.
If a single Tiger carrying the recessive gene managed to become dominant, he could successfully raise already a dozen cubs, who's in turn would produce more.

From there, today Kazi has more than 120 tigers, with max density of upto 15 tigers per 100 square kilometres. At this situation, some of them with the recessive gene are bound to come across each other after a generation or two. Reply
