Patient's question:
I want to ask if it's important that the baby has a gene mutation after the paternity test?Doctor's answer:
A genetic mutation may occur in paternity testing because each person has thousands of genes, and the frequency of gene mutations is very low, so there will be no significant differences. However, according to the principles of genetic recombination and the issue of dominance, it might be more common with the mother. Paternity testing is based on the fact that a child develops from a fertilized egg, which is formed by the combination of sperm and eggs provided by the father and mother, respectively. Paternity testing utilizes DNA hybridization technology. When a child's DNA single strand hybridizes with the DNA single strand of the father or mother, and the hybridization band appears at a certain proportion or above, it can be concluded that the child is their offspring.
