Full siblings share the same biological mother and father, maternal half-siblings share the same mother only, and paternal half-siblings share the same father only.
Do brothers and sisters have the same DNA?
Because of recombination, siblings only share about 50 percent of the same DNA, on average, Dennis says. So while biological siblings have the same family tree, their genetic code might be different in at least one of the areas looked at in a given test. That’s true even for fraternal twins.
What does it mean if you have the same mom but different dads?

Will 23andMe tell me who my father is?
23andMe can give you a glimpse at your biological parents’ DNA simply by showing you your own. Your parents each passed half of their own DNA onto you, so your genetic composition reflects theirs. *The 23andMe PGS test includes health predisposition and carrier status reports.
How accurate is 23andMe?
At the laboratory, lab technicians extract this DNA and run it through a machine that searches for each of the 700,000 SNPs that 23andMe is looking at. At this level, results from this test are 99%+ accurate. In other words, if 23andMe says you carry a variant on a specific chromosome, you likely do.
Can a DNA test tell if you are siblings?
A DNA sibling test will test the relationship between two or more individuals to assess if they are biologically related as siblings. Sibling tests can also be used to provide reliable parentage testing when one parent is deceased or unavailable.
How long does a sibling DNA test take?

Can one baby have two fathers?
Superfecundation is the fertilization of two or more ova from the same cycle by sperm from separate acts of sexual intercourse, which can lead to twin babies from two separate biological fathers. The term superfecundation is derived from fecund, meaning the ability to produce offspring.
