What would you like to do?
I think what you mean to ask is "is DNA testing reliable to determine siblingship in two individuals with the same mother but not the same father?" The answer is, yes, but it depends. DNA is the material that codes for the genes which are essentially the blue print for how we are made. We have 46 chromosome, 23 we get from our mother and 23 from our father. We also get some mitochondrial DNA from our mother only. So testing depends on the individual sex of the children involved, but using mitochondrial DNA, it is quite accurate, since all children born of a certain female should share this DNA.

that would be a half broher a half-brother
Same Mother, Different Fathers ... Half Siblings: Yes, if you have the same mother but different fathers then you are half brothers or half sisters. However, if you and a…nother sibling had the same father then you are not half siblings but brother and sister. It's the gene pool so it doesn't matter if your mother gave birth to you or not, if it's a different father then you are a half brother or half sister.No, if you have the same mother, you are not half siblings, only if you have different fathers, you are a half siblings. Nothing from the womb is half. Obviously the person who answered the question above is not very educated. This seems to be a misconception among the black community, (no offense... I'm half black myself). It doesn't matter if siblings share the same biological mother or father because you receive half your DNA from your mother and half from your father. So, to answer your question... it doesn't matter if you share the same mother or father, you're half siblings either way. Looks like the person above was sleeping in their science class or just a victim of misinformation.
Full sibling A full sibling (full brother or full sister), is a sibling that shares both biological or adoptive parents. Half sibling A half sibling (half b…rother or half sister) is a sibling with one shared biological or adoptive parent. A half sibling that shares the same mother (but different fathers) is known as a uterine sibling, whereas one that shares the same father is known as an agnate sibling. In law, the term consanguine is used in place of agnate. Half siblings can have a wide variety of interpersonal relationships, from a bond as close as any full siblings, to total strangers.
My father had an affair early in my parents' marriage. I found out at the age of 27 that I had "another sister". Now, due to the fact that we obviously have different mo…thers, I refer to her as my SISTER. Not 1/2 or whole. Nevertheless, "technically" she would be my half sister (bcs. we share the same dad.) My oldest sister (sharing the same mother AND father) is my whole sister. This is just my take on it. Simply how I feel. I love her regardless!
If you only share one parent, that makes you half siblings.
Half. FULL. If you have the same mother you are sisters/brothers. The child, if a non-bloodless delivery commingles with the mother's bodily fluid as well as blood, thus… making the children with the same mother FULL sisters/brothers. This has been the theory for many years only now within the last 5-10 years has there been controversy over this issue. In laymen terms, if a child is delivered naturally that child will intake the mother's bodily fluids as well as blood, which means the child literally has his/her mother's blood in their veins.
it depends on the circumstances...you would not be full siblings though you would be considered half siblings Basically, you're just half-siblings, though you could tell …people you were full siblings.
Blood type varies even throughout the family. it is possible but can also not be true
Can a DNA test be conducted between a brother and a sister who have different mother but the same father?
Yes, but the sex chromosomes could not be used.
What is the saying I was told that if you have the same mother but different fathers you are not half nor whole siblings so what does that make you?
Your half siblings. My best friend's mom married before she got married to the man she is married to right now and now my best friend has 2 half brothers.
A DNA test cannot give 100% proof of any relationship. It can only tell you what percentage of your genes are similar to another person's. For example, you might be 50% the sa…me as another person, but the test alone would not tell you whether that person was your father or your son or possibly even your brother. You would need to use other information (e.g. age) to establish that. Your DNA would be approximately 25% the same as your half-sibling's. But in fact it could be anywhere between 0% and 50% (although both these extremes are unlikely). A three-person test would also show what percentage of genes you each shared with your father. Both of you should have exactly 50% in common with your father, and all the genes you share with your half-sibling should also appear in your father's pattern.
How does having the same mother and different fathers make you a whole sibling verses have the same father and different mother Doesn't the dna of the father determine that?
I believe that if you have the same dad then you are not half bro/sis. I believe that it is the dna of the father that determines biological siblings. I have five children wit…h my husband and three of them have different mothers and I tell them all the time that they are NOT step anything or half anything because they all have the same dad. That's my story and I am sticking to it unless the world of medicine proves me wrong:)
yes sibblings wih
They are half siblings.
He is still technically your half-brother. But if you get along well, why would it ever matter? It is much easier not to differentiate and to call him your brother
