Subject: RE: [AZORES-Genealogy] Twins

 

I could be wrong, but I think that the genetic factor is applicable only
to the mother of fraternal twins.  That is, the mother has to release
two eggs at approximately the same time.  No matter how high the
father's sperm count is, there have to be two eggs.

For identical twins, of course, there is a single egg that divides.

I don't know anything about medicine, but when I was in high school
(many, many years ago) I wrote a term paper on multiple births for my
biology class.  I had twin cousins, and I was fascinated with the
subject.

If anyone in the group has a medical background, please feel free to
confirm or correct.

Nancy

My gg grandfather, Thomaz  Jose da Silveira was a twin. He & his
brother, Domingo were  baptized in the  Calheta do Nesquim parish on
Pico, on 20 July 1866. He had a grandson that fathered twins, a boy & a
girl, in 1938, in Washington, D.C.
