There was a woman with an identical twin. This woman got married and had a daughter. Then the woman died.
The husband then married the woman's twin sister and the husband had a daughter with the second twin.
If a genetic analysis were done would the results show that the two daughters were half sisters or full sisters?

The genetic analysis would likely show them as full sisters since it is an identical twin. However, for technical purposes and definition, having two biologically different moms (however slight the genetic differences may be) makes them half sisters.

What a question.
It seems logical that the daughters DNA would prove sisters, since the mothers are identical twins.

Genetic analysis would show that they are full sisters. That's because they had genetically identical parents.
Any other analysis would also show that Dad was a creepy dude.

The results would show full sisters.
Jon S is wrong my mother is an identical twin and they have been tested and have the exact same dna. Fraternal twins have different dna.

As you're no longer correct in any way with the help of blood and function never even been in the comparable kinfolk domicile, there must be no project, socially or otherwise. Your 0.5-sister's 0.5-sister isn't any sister in any respect to you biologically or legally. Any "social ingredient" may be in elementary terms in the narrow minds of the disapproving (except the girl is under-age)! life's too short to rigidity approximately such issues. you're a grown guy, do no longer ask for the approval of narrow-minded bigots - they're going to consistently discover something to disapprove of - merely tell them the way it rather is. end of.

Half. There is still a genetic difference between twins.
