Only if you are identical twins.
You have no blood line relation, You don't share DNA whatsoever. In this scenario putting an example; you and your half-sister share, let's say, the same father but not the same mother and your half-sister's half-sister share the same mother but not the same father. There is no shared DNA between you and your half-sister's half-sister.
If you have a sister with the same dad but different mom, then she's probably your half-sister, although she would have about 25% of the same DNA as yours.
Sister chromatids - two copies of the same DNA joined at the centromere.
DNA testing can determine if your brother, sister, father or mother are your true biological ones.
Yes, sister chromatids always have the same alleles because they are exact copies of each other formed during DNA replication in the S phase of the cell cycle.
I think this is related... No two people on earth can have the same DNA (genetics) so they wont be the same although they will be simalar though it is possiable to distinguish brother from sister, mother from daughter etc.
you could have a paternity test. Answer Testing using DNA from the father's father.
Just before mitosis, a chromosome consists of two sister chromatids joined by a centromere. Each sister chromatid contains one DNA molecule. Therefore, there are two DNA molecules in a chromosome just before mitosis.
Yes, two DNA molecules that are exact copies of each other are known as sister chromatids and are produced during the S phase of the cell cycle through DNA replication. Each sister chromatid contains the same genetic information as the other.

In creation a zygote from a father and mother ..DNA is made from 21 chromosomes from a father and 21 others from amother which the sperm and the ovule contains .. so every zygote from the same mother and father have at least 21 chromosomes common in their DNA because they came from the same source but they will differ in some characters according to the sequences of the bases on The DNA so the answer is yes
No, everybody does not have the same DNA. DNA is your unique signature.
