How Do Blood Paternity Tests Work?
When a child is conceived, he or she receives equal amounts of genetic makeup from both the mother and father. Each parent contributes 23 chromosomes, or sets of DNA, to their child from the egg and sperm during conception. Each chromosome pair in the child contains unique DNA sequencing, which can be used to determine the paternity of a child by comparing the DNA sequences to that of the father’s DNA sequences. Many women who may be unsure of the paternity of the father undergo blood paternity tests to test the DNA of the child to determine who the child’s father is.
