Yes, they can.
It is normal. Your blood type is determined by the genetics of your parents.
The sister's son would be the nephew of her brother.
If you mean in the case of one of your parents re-marrying - the children of the new partner are your step-brother/sisters.
A person's descendants are the children that he or she has. Siblings are not descendants. Of course, everyone has biological parents from whom they are descended, so in that sense everyone is a descendant of someone. But your sister is not your descendant. She is your parents' descendant.
Blood type is an inherited trait from both parents. If one parent were A- and the other A+. The kids can inherit either.
Of Course No.....You have to be blood brother and sister or brother and brother unless your father was to marry his mother, Pattie but then he'd be considered your Step brother not regular brother only Jazmin Bieber is his Regular sister
No they have incompatable blood types because the sister doesn't have the B part of the blood and her immune system would react against it. The brother may be able to get a kidney from his sister but other factors come into play also.
Not full brother and sister, but in sharing the same blood line ofthe mother, you are considered to be related by half of the parentage, in this case, on the mother's side. Whether one becomes full brother/sister is a matter of love,compassion, acceptance, and the half factor becomes a matter only of legality. You are half brother and sister. You share your mothers blood but not your fathers.
the general belief is that Cleopatras mother was Cleopatra V of Egypt who was either her fathers sister or cousin experts are not sure but they are sure that Cleopatra V and Ptolemy XII Auletes were blood relatives
yes because there is no blood relation
No Naruto has no siblings, he is an orphan with no blood relations, however he refers to Sasuke as his 'brother' which he means in more of an emotional way than literal.
Yes they were king tut may have died because his parents blood lines crossed to close.----------His parents were brother and sister. His father was Akhenaten, and his mother is known simply as "The Younger Lady". Akhenaten has at least 5 known consorts with whom he produced children. Tutankhamun was married to his half sister. This was a fairly common practice. When your wife has to physically be a goddess, it makes for a rather... shallow... gene pool.
