DNA Blood Testing
DNA Blood Testing

DNA EXAM of Bio-Synthesis a leading provider of Private, Legal, and Forensic DNA Paternity Tests provides determination paternity based on blood type preceded DNA testing. Ddetermining paternity based on blood type preceded DNA testing and, like eye colour inheritance, was largely based on the work of Gregory Mendel. Theories about genes and human development eventually led great minds like Watson and Crick to unravel the DNA double helix model, paving the way for modern geneticists to sequence the entire human genome in 2001. The IDENTIGENE Blood Type Paternity Test demonstrates how ABO Blood Type and inherited trait theory is used to determine paternity.

Our staff works hard to make the DNA Identity Testing Center your choice of provider for all DNA testing services. We ensure superior quality, service and convenience to our clients. In our commitment to providing convenience, please know that we provide a free DNASwabTM Home DNA Collection Kit for use in all types of private DNA tests.

DNA and Parentage Blood Testing
DNA and Parentage Blood Testing
Blood samples are usually collected for parentage testing. Testing can also be done using cells from the inside of the mouth which are collected with a cotton swab (buccal swab). Tissue samples collected from deceased individuals may also be used for testing. In order to assure the integrity of the results, all stages of DNA and parentage blood testing must be conducted under appropriate safeguards.
Locus
Locus (with a hard "c", LOW-KUS)is simply a location in the DNA. The plural of locus is, loci (with a soft "c", pronounced LOW-S-EYE). Again, the DNA is a long string like object. A locus is simply a location in the DNA. Such locations, or loci, reside at specific places on chromosomes.
Chromosome
When a cell is getting ready to divide creating two daughter cells, it packs its DNA into bundles called chromosomes. Chromosomes are just bundles of DNA. For humans, there are consistently 23 pairs of chromosomes, each with a consistent size and shape. Chromosomes are numbered. Chromosome number 1 is the largest chromosome; chromosome number 2 a little smaller and so on. Among the 23 pairs of chromosomes there is a pair called the sex chromosomes.
Alleles
Alleles
Alleles (ALL-EELS') are just variations at a particular site on a chromosome. Since each chromosome has a similar chromosome partner (except for males with their X and Y chromosomes) each locus is duplicated. Loci can vary a bit. If a person has two identical versions of the locus, they are said to be homozygous (HOMO-Z-EYE'-GUS). If there is a difference, they are said to be heterozygous (HETERO-Z-EYE'-GUS).
Forensic DNA Testing
There have been two main types of forensic DNA testing. They are often called, RFLP and PCR based testing, although these terms are not very descriptive. Generally, RFLP testing requires larger amounts of DNA and the DNA must be undegraded. Crime-scene evidence that is old or that is present in small amounts is often unsuitable for RFLP testing. Warm moist conditions may accelerate DNA degradation rendering it unsuitable for RFLP in a relatively short period of time.
