Frequently Asked Questions

DNA testing allows us to differentiate ourselves individually from the rest of the population, and, by comparison with other individuals establish parency relationships (paternity, maternity, etc.). The DNA or deoxyribonucleic acid is different for every human (except for identical twins), being equal in 50% to each of the biological parents.

Genetic fingerprinting is also called DNA testing or DNA fingerprinting. DNA analysis is the technique used to distinguish individuals from each other using samples of their DNA.
Humans share the vast majority of their genetic material, so in order to distinguish two individuals we analyze the repetition of highly variable sequences called microsatellites.
The genetic fingerprint of an individual is unique, and remains unalterable. throughout life and after the death of a person, so that serves to reliably identify individuals.

When samples are not available from one of the parents, it is possible to do a paternity/ maternity test using the genetic profile of the paternal/maternal grandparents, in addition to the profile of the available parent. The statistical calculation allows us to obtain a accuracy rate that is comparable to the paternity/maternity testing standard.

For statistical reasons, the degree of certainty cannot reach 100%, the mathematical value reached will be resolute when both parents are involved. When alleles are present (forms of the same gene), compatible in all the markers analyzed, we calculate the probability that this person is the biological parent.

No, if the siblings are monozygotic twins (commonly called identical twins), they share the same genetic information; they are clones, so to speak. Therefore, it would not be possible to differentiate them through this analysis. However, dizygotic twins (commonly called fraternal twins) are different at the genetic level, as their resemblance is that of any two siblings.
