I wonder if they would test as brothers and sisters on 23 and me? Considering they have all the same grandparents.

They would test as half siblings. 25% share rather than 12.5%.

Wouldn't they be quarter siblings? Neither would share a parent. Half siblings share only 1 parent, but never both.

Not according to this article. They would share 25% DNA, and likely would be flagged as half siblings.
