Works with Mitochondrial DNA
A quick rundown of Mitochondrial DNA (mtDNA) vs Nuclear DNA (DNA):
It is present in hair, Nuclear is not. Mitochondrial DNA is inherited from your mother, it is indistinguishable from your mother's mtDNA, your grandmother's, etc etc etc. Males do not contribute to the mtDNA of their offspring. mtDNA is circular in structure vs the helix of DNA.

Mr Fetor looked at:
REG-15#6c : Brown hair, ~3/4 inch.
When using the Cambridge/Anderson Reference Sequence, CRS, (info here for those curious), he found 3 discrepancies.
16192
16256
16270
The same sequence discrepancies were found in Asha's blood sample.
Conclusion: The hair was Asha's.
**No one in Michael McClish's maternal line matched.
