Can two blood brothers marry two blood sisters from the same biological family

Too close for comfort.

What's wrong with it?

Yes, I've seen this.  When I was younger my very close friend's maternal aunt, married her paternal uncle.  She also had a younger aunt who was dating her younger uncle on the father's side.

Her mom and dad are still married.

I have not seen it happen. But i dont think its wrong. Well some culture dont allow it. Xx

There is nothing bad with it

Nothing wrong with it.

Is not allow in any yoruba culture, and by the way why is it that u want to marry from the same family with ur brother when there are lot of ladies in this country which u can propose to.
from my own point of view is not a good idea cos (1) there will be no respect btw the two sisters
2. is never done
3. i believe is forbidding
4. it may create controversy in the family

Its normal,bcus twins do same.

says who?

While I dont see anything wrong with it, I'm not sure I'll support such unions

lost of twins esp identical marry the same identical sisters. i know a few

Of Course yes (i cant dothat sha)! My Hausa brothers do that all the time, infact, in the north, not only can 2 brothers marry two sisters, you can marry your cousin (even 1st cousin) you sister/brother-in-law, your fathers friend, and the list goes on,

nothing wrong but the only problem is when comes to genetical defects eg diseases that can be passed through family genes

Yes.
It shows both families are extremely, mutually desirable.
