No, unless they are Identical Twins.
Normal siblings will on average share 50 percent of their genetic material, since they get half of their chromosomes from their mother and half from their father.

∙ 12y agoNo, every persons DNA is different, however, brothers would have very similar DNA. Many traits of the DNA are hereditary, but no two sets of DNA are identical. Much like a thumb print only far more complex.

∙ 13y agoIt is impossible for a brother and sister to have exactly the same chromosomes as the sex or gender chromosomes would have to be different for them to be boy and girl. Females have two X chromosomes and males an X ans a Y. This is why identical twins are always the same sex.

Would two brothers have the simIlar dna?
It is very unlikely that two brothers would have babies with the same DNA. That could only happen if identical twin brothers married identical twin sisters, and even then the mixing of DNA during reproduction makes this an extremely unlikely outcome.
Do simease twins share the same DNA?
sure, if youd like to think that. but perhaps they share the DNA... why wouldn't you think they do?
Why are identical twins so close?
Bear in mind that no two individuals are exactly the same. However, seeing that indentical twins result from the same fertilized egg with the same sperm, they are essentially clones of each other.
What percentage of DNA do humans share with a spider plant?
Humans share at least some genes (DNA) with all living organisms. As far as plants, it is around 15%.
Why do you look like your siblings?
You and your siblings share parents. Every time a child is conceived that child receives half of the mother's DNA (genes) and half of the father's genes. If the same mother and father have more than one child, they still only have the same genes to contribute, but they might be mixed in different combinations. That is why you resemble your brothers and sisters, but probably don't look exactly alike.
If my cousin and i are from first brothers would we share the same DNA?
Cousins would share up to 50% of the DNA.
When brothers marry sisters how close will they children's DNA be?
When brothers marry sisters their children's DNA will be closer that that of regular first cousins, but not as close as that of siblings.
Can two brothers with same genotype and blood group share the same DNA lab test?
Only identical twins from the splitting of the single ovum ( monozygotic) have identical DNA

Would half sisters have the same DNA?
Some of the same but not completly, they would have some from the parent they share but not the other one.
If my cousin and I have the same grandfather do we share the same DNA?
Some of your DNA will be the same! You are likely to have somewhere between 1/8th and 1/16th of the same DNA.
Do simease twins share the same DNA?
sure, if youd like to think that. but perhaps they share the DNA... why wouldn't you think they do?
How many brothers and sisters did King Tutankhamun have in all?
Six sisters, all older, but we don't know the names of all of them :(. We know they are his sisters via DNA analysis conducted in 2010.
Why do siblings look alike?
because siblings share much of the same DNA. if the parents are the same, then each child will have half it's DNA for either parent, so siblings will share an average of half their DNA, ending up with the similar characteristics that their DNA codes for. for siblings with only one parent in common, an average of a quarter of their DNA is the same.
Do brothers have the same x chromosome or asked another way can DNA determine between two brothers the real father of a daughter?
Yes, DNA analysis can distinguish between two brothers.
Who shares your mitochondrial DNA?
Mitochondrial DNA comes from the mother, so the mother's maternal line and all her children share the same mitochondrial DNA.
Is Cody Simpson and Cody Simpson related?
Yes; they are the same person. Therefore they share the same DNA.
