An example of a polygenic trait is human skin color variation. Several genes factor into determining a person's natural skin color, so modifying only one of those genes can change skin color slightly or in some cases, such as for SLC24A5, moderately.
Case 1 â The Alleged Father has Recently Passed Away. If less than a week has passed since the deceased died, then if permission can be obtained, fingernail cuttings and a hair sample with root attached can be used to extract DNA samples to establish paternity. It is a more complex procedure than a buccal swab, but the DNA matching is just as accurate.
Putative non-custodial fathers will be required to pay child support upon a finding of paternity by the court. DNA Paternity Testing will only be conducted by order of the court upon a finding that the mother cannot name the putative father as the legal and biological father of the child. The establishment of paternity affords your child legal rights and privileges that belong to any child born within a marriage.
