nope! only if your identical twins... I saw one of those talk shows where they were doing paternity tests .. and this girl slept with identical twin brothers and didn't know which one was the father.. well the baby's DNA matched both of them poor baby one is her uncle one is her dad and she will never know which one

Each brother has his own set of DNA from the father and mother. There are some things the same and some differences. Only identical twins where the egg splits are the same DNA. Each sperm gets half of the fathers DNA, each egg gets half the mothers DNA, the combinations can vary.

Everybody else is right - the answer is no.
Just wanted to add that you, on average, inherit 50% of the same genes as your brother.
But then 99.9% of your parents' genes are the same as each other, so it doesn't matter which parent you get a gene from, if both parents have the same one.
So you have only a fraction less than 100% of the same genes as your brother. But not 100%.
You get almost exactly 100% the same DNA as an identical twin, but DNA doesn't get copied perfectly, so even that is not quite 100%.

no you may make you're taking a DNA try except you want to, the element you should locate out what does your brother stand to earnings from this documents.... you realize you have a similar mom, possibly he's only involved, i understand they are costly to accomplish that i could attempt to be sure the justifications in the back of it in the previous finding out no count number if to do it or no longer. x

No, close or similar in some parts of the DNA but not exactly similair. Nobody has identical DNA to somebody else.

It is the same thoough blood and hair samlpe they woud carry the same genetic make up the lines in dna would line up the same like a fingerprint would the way shin line work in your fingers.

You get half your DNA from Mom and half from Dad. But siblings (unless identical twins) do not necessarily get each half from the same parent.

very very similar dna, but not exact, the father and mother both passed on their genes, but each egg and sperm are slightly differenr, identical twin's dna would be identical, sice the same egg and sperm spawned them both

No, they do not. There are many similarities but everyones DNA is distinct just the same as snow flakes.

No, everyon'es DNA is different. You might have some of the same genes, but no two DNA's are exactly alike. Even twins!
