I share 53 segments of DNA with a relative. I’m currently not sure of my exact relationship with them however, but Ancestry.com shows us as cousins with confidence being extremely high. This person is 82, I’m 53. He’s the age of my parents. Is it possible that he’s actually an uncle or my biological father?
Based on your information, it is hard to say the relationship based solely on the number of segments. The number of cM is the more important measurement.
However based on my experience, if the match was your father, then he should be in the predicted relationship of Parent/Child. Just as a reference, my parents show up as around 3450 cM. My dad shares 68 segments while my mother has 87 segments. My Aunt and half-sister both show up as a predicted relationship of Close Family - 1st cousin. (~1700 cM with 66 segments and ~1400 cM with 56 segments respectively) All my actual 1st cousins (3 have tested so far) show up with a possible range of 1st-2nd cousin (range of 692-793 cM with 28-31 segments)
I am positive the match is not your father. If the range reported is Close Family-1st cousin, based on the age difference, Uncle seems the most likely.
