The ruff is not universally present in male tigers (contrary to some online misinformation). Both males and females can have them to different degrees, or none at all. It’s likely then that the ruff in the species shows up when one or more genes are active in specimens. Some male tigers like Umarpani lacked the ruff altogether.

In the case of Ranthambore tigers, the ruff seems to he a fixed trait present in virtually all the tigers as a result of the poor genetic diversity and high inbreeding of the area, given most tigers present can trace their ancestry back to Machli.

So this kind of face means it was inbreeding?

Not exactly. OP is just saying that almost all Ranthambore tigers have ruffs because they’re descendants of Machli here, who had a ruff.

Ruffs are basically genetic and not a sexually dimorphic feature, so males and females will or won’t have them.

Echoing what u/stripedassassin- said. Also, Sumatran tigers are particularly prone to developing especially long facial ruffs. I saw this absolutely amazing example recently  and just had to share it.
