I not only didn't see any mention of non-communal "quaternary marriages" mentioned in this article, I couldn't find a single mention anywhere on wikipedia. Could quaternary marriages be mentioned or even have its own article? I learned about it earlier today in the letter section of Popular Science and this was basically the only worthwhile web reference I could find outside of discussion about group marriages: 
Changes made along with addition of Turner Syndrome
I rearranged some of the sentences and added a few words for more cadence and ease of reading. I also deleted the word "vanishing" from the reference to the occurrence of male/female monozygotic twins because it implies that the phenomena is decreasing and there is no evidence presented to support that.
I am new to this so if anyone has any pointers on my reference I'd love to hear them. A lot of the information available on Turner twins is hearsay and I tried to pick an article written by a medical professional for general audiences. — Preceding unsigned comment added by QKB (talk • contribs) 11:33, 18 April 2015 (UTC)
Cute, but trivial, story for deletion
In the "Delivery Interval" section, there is currently the cute, but hardly encyclopedic, paragraph:
A longer delivery interval can lead to twins being born in different places. In one instance a woman in the north of England gave birth unexpectedly to a baby at home; she was rushed to the nearest hospital, which was in Scotland, where she gave birth to the second twin an hour and a half later. One twin is English, and the other Scottish, although both share British nationality.
This Ripley's Believe It Or Not!-style paragraph adds nothing to a better understanding of the subject of twins. Furthermore, the source of the story (BBC) does not address the issue of the Englishness or Scottishness of either child, making the claim that these children, or their parents, will self-identify as English or Scottish totally presumtive on the part of the Wikipedia contributor. And finally, the location of one's birth is not the sole, or even primary, factor in determining ethnicity: if a Japanese woman had given birth in Scotland and then returned home with her baby (as the mother in this case did) the baby would not be considered Scottish (except, perhaps, in an interesting-cocktail-party-story kind of way).
