Is anyone here significantly familiar with polyembrionic citrus seed?

I have potted a volunteer citrus seed germination, which has two
seedlings
growing from the one seed, a condition known as "polyembrionic". Each
seedling has its own root. I vaguely remember reading something about a
decade ago, that one of these seedlings has the genetics of the
original
fruit and will eventually produce fruit true to the original fruit,
while the
other one will likely produce undesirable fruit.

MY QUESTION IS: Does anyone here know which seedling I can cut off,
thereby leaving the one which will eventually bear desirable fruit?

(Since it will be many years before fruit can be expected, I do not
wish to
maintain the one that will produce undesirable fruit.)
