The process uses a very small part of our Y chromosome for analysis.  The parts used are not used for any other purpose: They cannot identify hair or eye color, genetic diseases, etc.  They are sometimes called Ajunk DNA@ because the scientists don=t know what purpose it serves, BUT because it changes ever so slowly [average of one mutation every 500 generations for each of the loci or marker segment of the Y Chromosome checked] it is a great way to trace the linage of we men back many generations along our surname.    No one can be identified by their sample because the haplotypes are the same for many men.  




The portion of the DNA tested gives a distinctive "fingerprint" [haplotype] for a lineage rather than for an individual, so there is no risk of this data being of any use to anyone for personal identity.


Only the person providing a DNA sample and the Project Coordinator will know who provide what sample.


Unless the provider of the sample has given the Project Coordinator [Vince Correll] a signed “Release of Liability” form giving permission to list the results of  the analysis [haplotype] under their first and last names, only the Initials and last name will be shown in section 6 [Results] of this Correll DNA project. 


In due time I will send a “Release of Liability” form.   When it is signed and returned it will give me your permission to include your first and last name with your haplotype on the Results page of our Correll DNA Genealogy Project.  


 If the “Release” form [which comes in the sample kit] has been signed and returned with the DNA sample, Family Tree will notify the donor if there is another person with the same haplotype.  It is a great way for men who have the same haplotype, or nearly the same haplotype, to cooperate in future family history research. Remember, mutations do occur naturally over time, so up to 3 marker variations in a 37 marker analysis, still indicate a probable common ancestor.
