I have what is called a double match. Do you have information on that?

How many Centimorgans does 1 person have? I know you get 1/2 from mom and 1/2 from dad, but how many do you have altogether?

If you hav't get answer I can tell you that according to my knowledge it should be arround 7.000 cM.

Is this wording correct:
centimorgan is a measure of the probability that a shared DNA segment of a particular size will be swapped between chromozones during egg fertilization, which may determine the likelihood of sharing genetic traits.

I'm trying to find my father, I been talking to a man who maybe my uncle or half sibling I found him through DNA on ancestry. This is what ancestry says Shared DNA: 1,529 cM across 40 segments. Is that sound right, could he be either my uncle or half sibling with those numbers
