The alleged father, John P. Smith, cannot be excluded as being the father of the child, Bob Q. Smith. Signed and Notarized Where the alleged father is not the biological father. The alleged father, John P. Smith, is excluded as being the father of the child, Bob Q. Smith. For seven different genetic systems analyzed with the polymerase chain reaction, the alleged father, John P. Smith failed to match the obligate paternal allele present in the child, Bob Q. Smith. Signed and Notarized Sibling Study Only use the siblingship test when the parental samples are unattainable.
Results take several weeks to complete.
If the two alleged siblings share very rare genes, the results will report a high likelihood that the two individuals are full siblings. If the two individuals are truly full siblings but they only share genes commonly found in the population, the likelihood that they are full siblings is reduced greatly. This is because the common genes have a high probability of being shared out of coincidence. A 4 Two true offspring of the mother and father above could be A1,A3 and A2,A4. Thus, the two true siblings could actually have no genes in common.
