I get the same results as you do applying your script to your sample data. But, not knowing WHAT formula to apply under which conditions, I can't tell "what (you're) ... doing is right." And, I'm afraid, nobody without a profound background in genetics can.

Aside, your code might benefit (improved readability and understandability, ease of maintenance) from some structuring and, mayhap, simplification. Like e.g.

Code:

awk '
FNR == 1        {print $0,"weight"
                 next
                }

                {TMP =  exp (($2<=0.01) ? (1-$2)*25 : (0.5-$2)*0.5 )
                 print $0, TMP / (1 + TMP)
                }
'  file
SNP MAF weight
10:60523:T:G 0.013 0.560576
10:62010:C:T 0.01125 0.560792
10:69083:C:T 0.3581 0.51773
10:73537:G:A 0.005268 1
