Again this year the same branch on my Cara Cara tree is producing Washington Navel Oranges. Last year I noticed that branch was not producing pink fleshed Cara Cara, but rather the regular orange colored fruit. This year since the same branch is once again producing fruit with orange colored flesh that branch must have surely revered back to a Washington navel. For those that don't know, Cara Cara were originally a sport of a Washington Navel orange tree growing in Venezuela.
