Y-Chromosome ‘Adam’ and Me – Using Y-DNA to Trace Ancient …
https://www.dnainthenews.com/human-history/y-dna-haplogroup/
Markers found on the Y-chromosome are passed down from father to son and can be used to trace back the patrilineal ancestry all the way back to the genetic forefather of all modern men – the ‘Y-Chromosome Adam’. Maternal ancestry can also be traced, but this is through a different analysis of mitochondrial DNA.

Y-DNA testing is a way to trace your ancestry back into the distant past. You can see back thousands and even tens of thousands of years ago. But the trick is that it only traces back the paternal line. In other words, you can only see your dad (and his brothers), your dad's dad (and his brothers), and so on.

two main techniques are currently being used: mapping polymorphisms on the y chromosome to trace paternal ancestry and on mitochondrial dna to trace maternal lines.12,13both techniques take advantage of the fact that some genetic material is passed down unchanged from parent to child—in the case of the y chromosome, from father to son; and in …
Tracing my paternal ancestors through Y DNA
https://mountainsrivers.com/2020/06/30/tracing-my-paternal-ancestors-through-y-dna/
Tracing my paternal ancestors through Y DNA Posted on June 30, 2020 The human Y chromosome is a male-specific sex chromosome. When mutations (errors in the copying process) arise in the Y chromosome, they are passed down directly from father to son in a direct male line of descent and define a tree of Y “haplogroups”.
How do you use a Y DNA test to trace your paternal …
https://nebula.org/blog/y-dna-test/
The Y chromosome makes a genetic distinction between males and females. It is also called a “sex chromosome” because it determines whether a child will be biologically male or female. Males receive one X chromosome from their mother (who has two X chromosomes) and a Y chromosome from their father (who has one X and one Y chromosome).
Forensic use of Y-chromosome DNA: a general overview
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5418305/
Y-chromosome polymorphisms are applied for inferring the paternal bio-geographic ancestry of unknown trace donors or missing persons, in cases where autosomal DNA profiling is uninformative. In this overview, all different forensic applications of Y-chromosome DNA are described.

The number of generations traced by a Y-chromosome DNA test depends on the type of test taken, short tandem repeat (STR) or single nucleotide polymorphism (SNP). STR tests are able to trace a male lineage within genealogical times and into historic times. Your genealogical connections will be shown on the Y-DNA – Matches page of your myFTDNA ...
