OUTLINE
• DNA Testing Uses
• Mitochondrial DNA
• Y Chromosome DNA
• Autosomal DNA
• Czech DNA Project
• Moravian Valach Paper
• Helpful Hints
DNA Testing Uses
• “Normal Genealogy”-connecting family
branches
• “ Deep Ancestry”
* Prehistory
* Deep time depth
DNA Testing Uses(cont)
• Determine if two people are related and
descended from the same ancestor
• Confirm your family tree
• Find out if others with your surname are
related
• Confirm surname variants
• Find others to whom you are related
DNA TESTING COMPANIES
• Family Tree DNA
http://www.familytreedna.com
• 23 and me

• Ancestry.com

MITOCHONDRIAL DNA
• Passed from mother to children
• 16,569 bases
• 33 haplogroups
• Haplogroups are continent specific
• Seven are specific to Europe
• 95% of all Europeans
• Haplogroup origins-10,000-45,000 years ago
mtDNA STUDY RESULTS

Y Testing
• Several different techniques
• Short tandem repeats(STRs)
• Commercially available-9-111 markers
• Single nucleotide polymorphisms (SNPs)
• Full Genomes-$1250
• Big Y-FTDNA-10 million bases-$495

AUTOSOMAL DNA
• 22 of 23 pairs of chromosomes are called “autosomes”. The 23rd pair determines sex.
• Inherited from both parents
• Nearly complete genetic record
• Recombination
• DNA signal drops rapidly with distance of relationship
• FTDNA, 23 and Me, and Ancestry provide autosomal DNA testing
CZECH DNA PROJECT
• Website:
http://www.familytreedna.com/public/Czech
• Over 600 participants
• For testing, contact:
Leo Baca: [email protected]
Joan Hudson: [email protected]
12 marker Y chromosome test: $49
mtDNA Plus test(HVR1 and 2): $49
Family Finder Test (autosomal DNA): $99
MORAVIAN VALACH PAPER
• “Y-chromosomal diversity of the Valachs
from the Czech Republic: Model for
isolated population in Central Europe”
• Croation Medical Journal, 2011.
• Authors: Edvard Ehler, Daniel Vanek,
Vlastimil Stenzel, Vaclav Vancata
CONCLUSIONS
• Moravian Valachs resemble more the
isolated Balkan populations such as the
Aromuns.
• Moravian Valachs represent a unique
Central European population model for
population genetics.
• Valach modal haplotype was not detected in
the Czech population.
VALACH MODAL HAPLOTYPE
• DYS 390= 24
• DYS 391= 10
• DYS 392= 11
• DYS 393= 13
• DYS 385a= 11
• DYS 385b= 14
• DYS 437= 15
• DYS 439= 12
