On average, you share about 25% of your dna with each grandparent, though real results range from roughly 15% to 35% due to random recombination.

Siblings share about 50% of their dna on average, but real matches vary from roughly 37–61%.

Half siblings usually share about 25% of their DNA, with real results often falling between roughly 17% and 34%.

Each child shares about 50% of their dna with each parent, though the exact pieces passed down are unique for every person.

You share about 12.5% of your autosomal DNA with a first cousin, though real matches usually fall in a broad range.

Humans share about 60% of their DNA with bananas, revealing surprising genetic similarities between humans and plants.

Half siblings usually share about 25% of their DNA, though real results can range from roughly 17% to 34% depending on inheritance.

In humans, each chromosome holds about 50–300 million DNA base pairs, adding up to roughly 3 billion base pairs across all 23 chromosomes.

The human body holds roughly 1.8×10^22 DNA base pairs, stretching to trillions of meters of DNA when added across all nucleated cells.

Each human cell holds about 6 picograms of DNA, which equals roughly 6.4 billion base pairs of human genetic code.
