“Human Karyotype Endogeny” was the topic of an earlier blog post.  The table above of human numbered (1-to-22) chromosome is from that blog post. The “vertical” is the chromosome numbers (1-to-22); and, the “horizontal” is alphabetical-ordered “gene-symbols on that chromosome.  The above table equates chromosome to gene-symbol summation. For example, chromosome Y = (DAZ+DMD+LWD+RBMY1A1+USP9Y) in … Continue reading Diana Elder, Nicole Dyer & Robin Wirthlin, “Research Like a Pro with DNA: A Genealogist’s Guide to Finding & Confirming Ancestors with DNA evidence”, 2021.
