How to know which blood type i have ? i mean if i know the blood type of my parents ? without a blood test, is it possible ?

You need blood test: You can calculate the likelihood of your blood type with a punnett square using the information from your parents. You will be able to narrow it down at least. But the blood test is so simple, it is the best way to find out.

See answer: Not allowing for + or -, unless your parents both have the same blood type (which you would then be), there are several possibilities if the combination of your parents you could be. Get blood test to determine.
