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.
How similar is human DNA to that of chimpanzees?
Human DNA is about 98-99 similar to that of chimpanzees, indicating a close genetic relationship between the two species.
Can a DNA test be conducted between two brothers who have a common mother to see if they have the same father?
Yes, a DNA test can be conducted between two brothers who have the same mother to determine if they have the same father. The test compares genetic markers shared between the brothers to assess the likelihood of them having the same biological father.
How similar is the DNA of dogs and humans?
The DNA of dogs and humans is about 84 similar. This means that there are many genetic similarities between the two species, but also significant differences that account for their unique characteristics and traits.

Do brothers have the same x chromosome or asked another way can DNA determine between two brothers the real father of a daughter?
Brothers do not share the same X chromosome. Therefore, DNA analysis can determine the father of a daughter between two brothers with high accuracy by comparing the genetic markers on the child's DNA with the potential fathers'. This is done through paternity testing which looks at specific genetic markers to confirm biological relationships.
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.

What further evidence would best substantiate that the two animals have a recent common ancestor?
The animals have very similar sequences in their DNA.
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 two DNA would have the same percentage?
DNA strands with equal percentage of guanine and cytosine (GC content) will have similar melting temperatures and will be more closely related. This means that DNA sequences with the same GC content will have similar stability and more closely matched hybridization properties.
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?
When the DNA is similar between two species it means there is a biological connection to each other.
If the amino acid sequences are similar in gorillas and humans why would you expect their DNA to also be similar?
Amino acid sequences are determined by the underlying DNA sequences that code for them, so similarities in amino acids suggest that the corresponding DNA sequences are also similar. Since both gorillas and humans share a common ancestor, evolutionary processes would have preserved many genetic sequences, leading to comparable DNA. Additionally, the genetic code is highly conserved, meaning that even small changes in DNA can lead to similar amino acid outputs, reinforcing the expectation of DNA similarity between the two species.
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.

Yes, a DNA test can be conducted between two brothers who have the same mother to determine if they have the same father. The test compares genetic markers shared between the brothers to assess the likelihood of them having the same biological father.
