Y-STR = Y Haplogroup/Paternal Lineage, ***NOT*** SNP

[VikLevaPatel]

Thanks to the DDC (DNA Diagnostics Center DDC Cincinnati) specialist for clearing this up for me.

STR and SNP are different testing types, but your Y-STR is your proper paternal lineage.

Maybe they (FTDNA, 23andMe, and others) should stop claiming that your SNPs determine your Paternal Haplogroups or Y-DNA Haplogroups.

[VikLevaPatel]

Y-STR and SNP results do not match and are completely different. In my case anyway. You can only belong to one haplogroup, not two.

DNA Solutions Australia: Y chromosome Paternal Ancestry E1b1b (Y-STR)
DNA Diagnostics Center (DDC) Cincinnati: Haplogroup E1b1b Paternal Lineage (Y-STR)

FTDNA: Y-DNA Haplotree - Confirmed Haplogroup is C-K466 (SNP)
23andMe: Paternal Haplogroup C-Z5896 (SNP)

mtDNA results are all correct:
DNA Solutions Australia: W6
FTDNA: W6
23andMe: W6

So STRs are more reliable? I thought snips were the reliable ones.

You’re C. Owd imbecile.

There is a high SNP shared between C and E. some old predictors do it incorrectly E as C as per some studies. Yours is probably C because E is extinct in India

If Ftdna and 23andme have told him through snp testing he is C then he is of course C and should stop spamming the forum with insane theories.

Yes, as ftdna and 23andme agree yours is C. There are reports of some C being misclassified as E came in some papers. That local test you bought is older Y-predictor that doesnt carry enough STR tests and SNP tests

77% Ancient European? What does that mean, you're related to Cheddar man or something? lol

A single-nucleotide polymorphism (SNP) test is a recent innovation into some Y-DNA tests.....

A Y chromosome test sequences and analyzes the Y chromosome in males. Since this chromosome is passed from a father to his sons, it can be traced back several generations. The two types of tests done are:
Short tandem repeat (STR) – suitable for earlier ancestry
Single nucleotide polymorphism (SNP) – helpful in determining more ancient ancestry

How far back do you want to go? 5ugyj0.jpg

So, SNPs (pronounce “SNIPS”) are recent innovations and determine "more ancient ancestry".

Um, no thanks. I'll stick with the STRs, the system of choice for forensic and paternity testing laboratories.

In my case, Y-DNA SNP results do not match with Y-DNA STR results.

Short tandem repeat (STR) typing is widely used for the genetic identification of individuals, in paternity testing and in forensic trace analysis. STRs make ideal markers for genetic typing for genealogy because of their rich diversity (polymorphism) and wide distribution. They can be characterized quickly and fairly easy in the lab.

STRs are useful genealogically, to determine to whom you match within a recent timeframe, of say, the past 500 years or so, and SNPs define haplogroups which reach much further back in time.

What Information Can Y-STR DNA Reveal?

Y-STR DNA testing is conducted on the short repeating sequences of the male genetic material and not the female equivalent. Moreover, every testing laboratory has its unique terminology and technical jargon when it comes to results.
Take a look at the attributes revealed in such a test.
Patrilineal relations: From father to son, grandparents, cousins, and any other unbroken male line
Marker levels and value: Name of the marker on the Y chromosome by segment, levels (12, 25, 67, 111), its length, and repeat structure
Familial matches: Depending on the service you use to test your DNA, you’ll be shown matches from its library to relatives and families
Y-DNA haplotype and haplogroup: The repeated sequences on specific markers on the Y-STR DNA is the haplotype. The segment of people with the most recent common ancestor (MRCA) dating back to hundreds and thousands of years is the haplogroup

This article reviews recent efforts in Y-chromosome short tandem repeat (Y-STR) and single nucleotide polymorphism (Y-SNP) analysis: https://www.csueastbay.edu/museum/fi...ev-y-short.pdf

One of the biggest problems with Y-SNPs has been the different naming schemes for haplogroup designation developed by the various Y-chromosome research groups around the world. Significant disadvantages for SNPs include needing 40–60 loci to obtain equivalent match probabilities as 13–15 STRs commonly used today and the greater difficulty with mixture interpretation due to a limited number of alleles compared to multi-allelic STR markers. It is likely that Y-SNPs will be used in a complementary role with Y-STRs rather than as a standalone approach for examining male genetic variation in a forensic context.

Genetics is a probabilistic science, and with the plummeting costs of gene sequencing came commercial interests. All of a sudden any company could set up shop, and in exchange for some cash and a vial of saliva, could extract your DNA from the cells in your mouth and sequence your genome. Alongside the behemoths 23andMe and AncestryDNA, dozens of companies have done just that.

Hi Vik,

Thanks for getting in touch.

We use SNPs for all three tests - autosomal, mitochondrial, and Y-DNA.

I hope that this helps.
Kind regards,

Emily

SNPs for all three tests

Damn it! I Should Have Known Better

Only a few companies have Y-DNA tests available.

I wonder why. Why am I not surprised? I know that Ancestry.com has stopped offering Y-DNA and mtDNA tests.

STRs are mainly relevant in the past 500 years, while SNPs go back many thousands of years.
