DNA testing among siblings

This isn't a common question, so I haven't been able to find anything by searching.

I have a character who has discovered who her real father is (just assuming he is) and finds out he is dead. There is no way to get any DNA from the man. Would it be possible for the woman's DNA to be compared to the man's sister? How identical are DNA between siblings? Could it prove the woman is the man's daughter?

I'm sorry if I've confused anyone. Feel free to ask anything for clarification. Thanks!

EDIT: Answered! Thanks to everyone who helped.
