Module 8 :: mtDNA & Y-STR
Topic 1 :: Introduction to mtDNA
Hypervariable Regions (cont.)
In the 1980s, scientists discovered that the probability of randomly selecting two people with the same mtDNA type was very low because there are thousands of mtDNA types among humans. Of the 700 nucleotides in the hypervariable regions, two maternally unrelated people have about 10 nucleotide differences.
