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.

Which two DNA samples are the most similar?
The question itself is not clear. Two cells that have just divided will have the MOST similar DNA. If we are talking about whole organisms or individuals, then clones would have the most similar DNA, similarly identical twins would have near identical DNA. Siblings have very similar DNA but not identical of course.
Can brothers and sisters share the same DNA?
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.
Do sisters have the same saliva?
Not based on real research but only logic and reason it is unlikely that cousins would have identical saliva. They may be similar, but they do have different DNA and different genetics. Each person is unique. It would be as if you said that they are the exact same person.
Can a DNA test be conducted between two brothers who have a common mother to see if they have the same father?
yes, although it helps to have a DNA sample of all parties (fathers included)
When DNA separates into two strands the DNA would most likely be directly involved in?
It would most likely be directly involved in replication.

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.
Can brothers and sisters share the same DNA?
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.
Can paternity be found in the DNA of two brothers?
As long as one knows who his father is. Otherwise, you're just determining they are brothers.
What further evidence would best substantiate that the two animals have a recent common ancestor?
The animals have very similar sequences in their DNA.
What species would the theory of evolution predict that human DNA is most similar to that of?
The two chimpanzee species Pan troglodyte and Pan paniscus.
If two species have similar DNA what hypothesis is supported?
The hypothesis supported is that the two species share a common ancestor and have evolved from a common gene pool. This similarity in DNA suggests that they are closely related evolutionarily.
Is a person's DNA likely to be more similar to the DNA of his or her biological parents or to the DNA of one of his or her cousins?
It is more likely to be similar to his or her parents because they get half of their genetic code from their mom and half from their dad, whereas cousins are only related to you by one set of grandparents.
How is your DNA similar to your mothers?
(Pending a more complicated answer. :-) Exactly(?) half of your "Nuclear" DNA (DNA in the nucleus of your cells, nothing to do with nuclear energy!) is identical(?) to your mother's. All(?) of your "Mitochondrial" DNA (DNA in your "Mitochondria") is identical(?) to your mother's. (Two reasons for the the question marks would be mutations and transcription errors.) See the links.
How does the DNA of a chimp compare to the DNA of a human?
Chimps have one less chromosome than humans. that is why if we try to interbreed we could never create offspring...well only in rare cases... but our offspring would have down syndrome... or something of that extent.
Do sisters have the same saliva?
Not based on real research but only logic and reason it is unlikely that cousins would have identical saliva. They may be similar, but they do have different DNA and different genetics. Each person is unique. It would be as if you said that they are the exact same person.
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
