A study of mitochondrial DNA sequence polymorphic positions in the greek population and application to forensis casework

Abstract

In order to identify polymorphic positions, to determine their frequency in HVI segment of mt-DNA and create a data base of Greek population, the HVI segment of 100 unrelated individuals from Greece were amplified and directly sequenced. Sequence comparison led to the identification of 86 mitochondrial lineages. The most frequently occurring lineage comprised 8 individuals, the second one 5, the third one 4 whereas near all the others types of HVI segment sequences were observed in only one individual. Sequence variation is mostly caused by nucleotide substitutions. As compared to nucleotide substitutions, the frequency of transitions were predominate to tranversions with proportion 75:30. Concerning the type of transitions, pyrimidine s were predominate to purines. Specifically, the rate was 58:17. Sequence variation caused by insertions or deletions was registered only two times, two insertions were noticed in two different samples and one deletion in one sample. As a result of seque ...
