Happy Y-Chromosome Day

Seven Copies of the same Y-Chromosomes I just meet with my father, my two sons and my three grandsons (seven copies of the same Y-Chromosome).  I know of and other four copies (my father’s brother’s, a second cousin, a nephew and grand nephew).  Of course there must be more copies but I do not know who possesses them.  The copies that I know about came to San Francisco with my great grandfather in 1900 from what is now Poland but was Galicia at the time.  But with all the work being done with genetics, I may find some other copies someday.
