Half-Blood.
No they cannot. They can only have a child with type A or type O blood.
If the child IS pissing blood and puss, then this kid is messed up.
If the child is Rh positive, and it is the mother's second child, the mother's antibodies will attack the child's red blood cells when the blood becomes mixed during labor. An injection called RhoGAM will be administered to the mother right before delivery to prevent any attack of fetal red blood cells.
yes
Yes. your sibling's sibling's child. Yes. 2 siblings. Basically your niece's first cousin is ur niece/nephew as well
Your nephew's first cousin may or may not be related to you, depending on how the cousin is related to your nephew. Your nephew's cousin may be your child, or the child of one of your brothers or sisters. Your nephew is related to you by being the son of your sibling. That sibling has a spouse who may also have borthers and sisters. The children of any of those brothers and sisters are also your nephew's first cousins, but are not related to you.
A child.
A first cousin is the child of your parent's sibling while a nephew is the child of your sibling. That makes the nephew more closely related to you than the first cousin, unless the law in your place of residence defines things differently.
no she is an only child
Well either you had a child with your sibling or with your spouse's sibling.
If you want to look at her that way there is nothing stopping you, but generally she would not be thought to be related to you. "In-Law" relationships are usually limited to the spouse of your child, the parent of your spouse, the sibling of your spouse and the spouse of your sibling.
Yes, your niece is the daughter of your sibling (sister or brother), so there is continuity of "blood" (i.e., genetic descent) from your common parent(s), assuming your sister/brother and her/his daughter are not adopted.
