I'm curious how the highlighted is figured? If they have the same father, they have 50% of the same DNA. The same as if my father had had a child with a woman other than my mother, that child would be my half sibling.

wishes4kissez - 2016-04-01 2:33 AM They don't necessarily share the same 50% from the sire though. Yes he passed on 50% of his genes but which 50% he passes varys and because of this even full siblings may share as little as 25% of the same DNA. But I also do not understand how they wouldn't be considered half siblings. I have heard people say you can breed two half siblings by the same sire to one another but never two out of the same dam. There was some clever rhyme that went with it something about a womb but I can't remember it lol. I wouldn't ever breed siblings of any sort together but always wondered what difference it made when people did!
