Answer:
My friend does not (or you can use doesn't) have sisters.
Explanation:
The word "don't" and "no" in the same sentence create double negatives which is inappropriate in an English sentence so, the sentence can be modified to only contain one negative (which is "does not" or "doesn't") to create the sentence "My friend does not have any sisters."
I hope this helps! :) sorry for the late answer!!!
