results expected

I am expecting my half sisters results soon (family finder) Will I (we) be able to tell if she is a half sister or full sister by these results?
What do I look for?
Thank you...

Good question!

I had thought that it was a clear-cut answer, but the Family Tree DNA Learning Center says otherwise (the FAQ title does not reveal that, but the example given is for a half-sibling). Maybe someone could offer an explanation?
Can Family Finder tell the difference between a sibling and a cousin?

FTDNA will give relationship range on your match page.

To see Suggested Relationship download you matchlist .csv

For instance, attached is a picture representing My Grandmothers, my Father's, 2 paternal Uncles, paternal Aunts and the paternal 1st cousins .csv file showing what relationship is listed on matchlist (Relationship range) and the narrowed down Suggested Relationship.

Not all Suggested Relationships are correct, but the majority have narrowed it down correctly

Thank you for the information. I will wait now and see just what the results show before I post again...thank you

I had my brother tested and his results came back with the relationship listed as parent/child or full sibling. We had a chuckle over the parent/child since we're only 7 years apart, so we went with full sibling.

The test labeling of relationships is based on the amount of DNA you share with a person. A half sibling would have less shared DNA since the DNA shared would only becoming from one parent. And siblings don't get the exact DNA from a parent that another sibling would. Full siblings would share in the area of about 50% DNA. Grandparents, aunts, uncles, 1/2 siblings and double first cousins are all in the same range of sharing about 25% DNA.
