Two blood tests can check for antibodies that attack red blood cells: the direct Coombs test and the indirect Coombs test. The direct Coombs test is done on a sample of red blood cells from the body. It detects antibodies that are already attached to red blood cells.
1 Marker: A specific place on a chromosome with two or more forms, called alleles, the inheritance of which can be followed from one generation to the next. 2  In Y-chromosome DNA testing, this refers to non-coding Y-chromosome DNA.3  Numbers designate the individual DNA segments. For example, in humans, one allele of the eye-color gene produces blue eyes and another allele of the eye-color gene produces brown eyes. 2  Administrator: Also known as a Project Administrator, Group Project Administrator, Project Manager, Coordinator and Co-Coordinator.
These 10 facts about space will blow your mind. Genetic markers are sequences of DNA which have been traced to specific locations on the chromosomes and associated with particular traits. They demonstrate polymorphism, which means that the markers in different organisms of the same species are different.
