If siblings have the same parents will their DNA be similar race wise or can they be different?

Question

If siblings have the same parents will their DNA be similar race wise or can they be different? My father and I had our DNA tested. He is Black (46%), white (41%) and American Indian (13%) and I am black (44%) white (32%) and Amer Ind (24%)
Would my Mom be more American Indian than we thought?

Will the rest of my brothers and sisters be black/white/ American Indian like me percentage wise or have more black or white in them? Or could my Mom also have say Asian and my sister or brother have Asian in them that was not reflected in me
...Or do the genes just come out and portray us differently--Within the same parents.

I would think that if siblings have the same parents, their genetic make-up would be the same. Although hair texture and color, eye and skin color change even with the same parents would race change as well?

COULD WE HAVE THE SAME PARENTS BUT ONE HAVE ASIAN IN THEM AND THE OTHER NOT BECAUSE MY MOM HAD IT and it did not show up in me?

Answer 1

pretty wild i don't really have an answer but i wonder about my family because my dad is an identical twin and my mom is an identical twin (she was she has pass on, but her twin is still alive) anyway my mom and dad got married and his twin met my moms twin at the wedding a year later they got married and my uncle and aunt have 4 boys while my mom and dad had 4 girls we all look similar (more so than most cousins) and we all sound alike i would love to try to get our dna tested just to see i always have seen us as more than cousins almost like siblings seeing as our parents were both identicals who married each other i am curious and maybe i can talk a few of them into getting tested you'd think we'd all match sorry for no answer i just thought it was a neat question and thought i'd share my weird family history none of us kids ever had twins either thank the lord..

Answer 2

It is not because of a disease. Here's how it could happen. One parent has B positive blood. The other parent has A Positive. The child is B positive. The parent with type A blood couldn't donate. And the sibling is A positive. The sibling couldn't donate. Rh factor could be a problem' There are other tissue type issues that could affect donor suitablity. Many times you'll see pleas on the news for donors. None of the patients family members were suitable and the search has to go out into the community. Answerer # 5, you are thinking of Chimera or Mosaic

Answer 3
