Do Family Members Really Share The Same Blood

Can blood relatives be family members?

Yes in fact that is practically the definition of blood relative.Wiktionary says-blood relative -A person who is related to another through a common ancestor, and not merely by marriage or adoption.The Free Dictionary says -one related by blood or origin; especially on sharing an ancestor with another.So that’s exactly what blood relative is, family.Now if you were to ask can family be blood relative? I’d say they wouldn’t have to be. First in the case of adoption and secondly when you have friends that you care about like you would think family should care. I have a few special friends like that. One guy I’ve known since the 3rd grads and we’re now 58 years old. He’s my brother from another mother.

Can all members of the same family unit have different blood types?

Easily. Imagine a family, parents and 2 children. Say the mother is type AB+, the father is type O-, and they have kids who are A+ and B-. Sound implausible? It’s entirely possible based on genetics.Mother’s genotype: AB+-, expresses as AB+Father’s genotype: OO—, expresses as O-First child’s genotype: AO+-, expresses as A+Second child’s genotype: BO—, expresses as B-It’s just a question of how different genotypes produces phenotypes.

Does every member of a family have the same blood group?

No - there is no reason that Mother and Father will have the same blood group as they should be unrelated. As for the children it largely depends on the parents blood group. There are 4 main blood types A,B,AB and O. The general rule is that 2 A’s cannot produce anything with a B in and 2 B’s cannot produce anything with an A in. Anything else is possible except for 2 O’s which will always produce an O.

Do you agree that family members are not only the people who share your blood? Why or why not?

I do not believe a person who does not share your direct blood line should be considered a family member. Although I think sometimes bonds between people outside of a Family can sometimes be stronger than those within a Family, I think that it's important to differentiate the two.Part of the reason why I think this is because there is paperwork that clearly defines who is "officially" apart of your family. This can have Legal and sometimes Moral or Religious obligations which might not be required or expected for someone who is just a close friend, or not related by blood.There are also medical concerns: If a family member needs an organ transplant, doctors often look towards close family members for a match before resorting to a donation waiting list. In a similar vein, susceptibility or be predisposed to certain ailments or conditions might not be relevant were the people not related by ancestral roots.Additionally, there are problems with ambiguity: Perhaps you consider someone to be the person you are closest to in the entire world. Can you say without doubt that they feel the same way within their own mind? This can attempted to be proven through acts like Marriage or similar ceremonies, but even then there is the chance for Divorce. The truth of the matter is that there is the option of choice. Choice makes all the difference in my opinion when it comes to the definition of "Family". As the saying goes: "You don't get to choose your family." That is to say, for good or bad, you are related to some people by bond of blood and not others for that same reason. Whether the matter of sharing that blood plays a role in your perceived closeness to that person is another matter.In my mind "Family" has very clear, very specific definition, and it doesn't make much sense to try and redefine it.
