Linked to a Question in News

[China Doll]

Evening All,

While discussing the story about twins marrying and the fact that this was actually completely untrue some of us got in to pondering about doners.

An expert has said that it is becoming more likely that half siblings could marry simply because their father is a sperm doner.

Is this actually that likely? Are doner's 'contributions' spread out over the country? (Every way I phrase that question sounds wrong!) Are there genetic implications if half siblings married.
