How much DNA do we share with siblings?

Because of recombination, siblings only share about 50 percent of the same DNA, on average, Dennis says.

That’s true even for fraternal twins..

However, because all populations are genetically diverse, and because there is a complex relation between ancestry, genetic makeup and phenotype, and because racial categories are based on subjective evaluations of the traits, there is no specific gene that can be used to determine a person’s race.

Can you tell someone’s age by their blood?

The levels of this enzyme change in the body between childhood and adulthood. Researchers completed the study by synthesizing human blood.
