A quick definition of genetic-marker test:
A genetic-marker test is a medical test that helps determine if a man could be the father of a child. It uses tissue samples and analyzes DNA to provide a more accurate assessment of paternity than blood-grouping tests. This test is often used in paternity and illegitimacy cases and is abbreviated as GMT.
A more thorough explanation:
A genetic-marker test is a medical procedure that analyzes DNA in tissue samples to determine the likelihood of paternity or illegitimacy in a child. This test is more precise than blood-grouping tests and is commonly used in paternity cases.
For example, if a woman is unsure who the father of her child is, she can have a genetic-marker test done to determine the probability of paternity for each potential father.
Another example is in cases where child support or custody is being disputed. A genetic-marker test can be used to provide evidence of paternity or lack thereof.
