The Casey Surname DNA Project

Hi,
My maternal line is Casey, so I am unable to submit a test myself. However, I have 2 male cousins who are Caseys and have had y-chromosome DNA testing done in a different genealogy project.I also know of several other Caseys who were involved in this project. Can they submit their test results to this project? Do they need to test again to be involved in this project? Do they need the approval of the Doctors that sponsored the previous test?
Thank you,
Bernie

It looks like the ole Casey-DNA is starting to squirm a bit in the petri dish. We've had two new members join the FTDNA project, and two new members register on this site. Before you know it, we'll grow into a real sampling of the Casey gene-poll. Keep it up, and spread the word!

Does anyone know when there will be a chart posted which will show comparative results of the DNA project and indicate the earliest known ancestor? Lacking a chart, is there anyone who matches anyone else yet? Given that there are so few participants, can we just reply with who our earliest known ancestor is? (I'm a female represented by my male cousin in the DNA project.) We're descendants of Daniel Casey, b abt 1760, probably in Virginia.) Thanks, Joyce

Is anyone else researching any Casey's from Virginia?

The male y-chromosome is used to trace origins of males in modern populations by studying the mutations that accumulate in the non-recombining part of the y-chromosome. Using y-linked microsatellites as markers of variation, phylogenetic relationships of the chromosomes present within a population can then be deduced.

Elementary genetics provides us with the fact that the 23rd chromosome, in the human genome, is the chromosome that determines sex. Males have both an "X" and a "Y" 23rd chromosome, but females only carry an "X" for their 23rd chromosome.
