You need to distinguish between two different measures of similarity. One
compares on all single SNPs tested, and you and a sibling will match roughly
85%. The second is the degree of similarity on shared segments, where you
and a sibling will share about 50%, usually between 45% and 55%.

Where are these percentages? My dad's sample matches mine at 48.43% DNA
Shared. Are you referring to the genome compare % similar? He and I are
83.93% similar there, implying my parents were genetic strangers according
to the formula below and both being Ashkenazi I would think they would be
closer than genetic strangers.
