Brother A marries Sister A, and Brother B marries sister B.
Are their children something closer than normal cousins?

hello....you have gotten alot of WRONG answers ....
they would be "double-first cousins"...
their blood line would be almost ..not quite..like brothers and sister...as close as you can be...and not be brothers and sisters.
I know cause my husband has "double-first cousins".
If my sister had not lost her baby..then our children would also have been...2 sisters married 2 brothers....been married for 40 yrs.
God bless

Probably the best question on here this week - brilliant. The red wine has not quite got the better of me -yet! I see exactly where you are coming from, but I do recall the variation boxes completed for GCSE science. Even if male twin A married female twin B and brother twin A married sister twin B their offspring would still have sufficient variation not to be considered siblings. They would be cousins BUT there is a possibility that the parents could give birth to near identical offspring. On the other hand, they could tick all the other boxes and be very different. A very interesting question. Wish I had thought of it!!

If both the mothers and the fathers are identical twins. Then if a DNA test was done on their children, even though they are cousins, it would actually show that they are brothers and sisters. Because the parents have the same exact DNA. So the children from these relationships have the same exact genetic make up. Like siblings do.
It is also a fact that if one identical twin male had a baby with a woman, and you test the baby both men would show as the father. Same with women who have baby's, both twins would show as the mother.

yes, they are double first cousins.
And to the first answerer: Its not "ew!" Its not inbreeding! LOL the twin guys and twin girls are not brother and sister! Imagine if your sister married your husband's brother. Its the same thing. you can also get double first cousins even if the parents are not twins.
I actually have an interesting family tree....my dad's brother married my mom's cousin....so my cousins are both my first cousins on dad's side, and third cousins on mom's side! (all with no inbreeding, thank you very much!)

That has happened in my family. Two brothers married two sisters. Their children are double first cousins.

In my mom's family, a couple of my grandma's sisters married my grandpa's brothers. And we always called it "royal cousins"... I don't know if that's exactly the same, but that's what we call it.

They would genetically be brother & sister if both parents were identical twins.

There is nothing closer than normal cousins. That is all that they would be.

How is that eww..?
They would be first cousins with identical, almost matching DNA...but that's about it. [if they were identical twins]
haha..this is an interesting question..
me and my sister are twins..
and it would be wicked if we were to marry twins.
