This outlines a Y-Chromosome Presentation by Richard Hill that may be scheduled in person or online through the Contact form.
With so much focus on autosomal DNA tests, many people overlook Y-chromosome testing. Yet Y-DNA’s uniquely male inheritance path lets you do things that cannot be done through other test types.
While only males have a Y-chromosome to be tested, female genealogists can usually find a suitable male to represent their paternal line, e.g. their brother, father, paternal grandfather, or a son of any of those men. By testing suitable subjects, you can use Y-DNA tests to check any paternal line in your family tree.
The sex chromosomes X and Y
The Y-chromosome inheritance path
Narrower and deeper than autosomal DNA testing
Confirm descent from known male ancestors.
Find genetic relatives who share a male ancestor in the direct paternal line
Find surname of a male’s biological father…for adoptees and donor-conceived
Define your paternal haplogroup to trace ancient geographic migrations
Much more than Y-DNA sampling on some autosomal DNA tests
Family Tree DNA
25-year sample retention
Short Tandem Repeats or STRs
How many markers to test?
Different thresholds for a match
More markers increase resolution
Can order more up front or upgrade later at a higher total cost
