Yes....if both parents are carriers of type "O" then they have a 25% chance of having a child with type "O" blood type (O is a recessive trait). The child would have to receive the recessive "O" from both parents. Regarding the Rh factor. If mom is a carrier of the negative Rh factor, then there is a 50% chance that the offspring may carry the Rh negative factor. Hope this helps...

How to Beat a court appointed drug test?

There are very few ways besides using someone elses urine and devising a way of wearing it on you and expelling it into a cup on command. This of course depends on if the test is to be witnessed or not. If it is not witnessed it is far easier but keep it tight to the body to keep it warm as there are lots of places that de a temperature test right away to make sure that it is warm because urine out of the body is heated. That's why you will notice no hot water or heaters of any kind in a urine test room with out supervision..

If you are to be watched they usually just standin the room and a baggy with a tube attached can be strapped to the leg and then keep the end of the tube clipped off and when you need to pee you just unzip and pull out your penis with the tube on the side and unclip and "pee"\\\

A littlecreativity and it is really quit easy ..Do it at home a coupletimes first cause you will not only get another charge for this but you will look like a fool when you drop a bag of urine all over yourself and the floor with a bag etc/...

Does an employer have to disclose what kind of drug test or what drugs they want tested?

Not to the test subject, they don't.

Most employers who drug test will specify a "standard" test for them. Quite often it's just the "SAMSHA-5" drug test--pot, cocaine, PCP, opiates and amphetamines/methamphetamines. But the employer can specify other drugs--barbiturates and benzodiazepines are commonly tested for. They can also ask for specific tests--they can ask for prescription drug abuse screening, tobacco, alcohol, whatever they want. I think there are some protected classes--they can't ask that you be tested for AZT, which is an AIDS drug, or Trobicin, which cures gonorrhea.

But yes, they can send you in to be tested for any drug they want. There are even drug tests that will look for hundreds of drugs at once--they cost several hundred dollars so they're used for stuff like checking people into rehab (where you want to see EVERYTHING the patient is on) or trying to treat a drug OD when you don't know what the patient took.
