Who's the daddy? The answer to that question can now be obtained by a quick trip down to your local Rite Aid drugstore, who have just begun stocking the $150 DNA paternity tests.

To find out whether the kid you've been raising all these years is really yours, all you need is a cheek swab from the mother, the child, and the man. Send off the swabs, and 3 to 5 days later you'll have your answer.

It is important to know that the results of the drugstore DNA paternity test is not admissible in court, so if you want to the real daddy to pay up, you'll need to go the route of a traditional, more expensive DNA test done at a medical facility.

The DNA Paternity Test Collection Kit recently went on sale at 4,363 Rite Aid drugstores throughout the U.S. According to the test's manufacturer, Identigene, the tests have been selling on a trial basis since November in California, Washington and Oregon, where they're already a hit.

With the relatively inexpensive DNA test available on the market, what will this mean for the trashy daytime talk shows who's sole focus is paternity disputes? And what about actual human behavior... will men be less likely to deny that the baby is theirs? Will women be less likely to blame whatever man happens to be around for their unexpected pregnancy? Only time will tell.
