Humans share around 60 percent of their genes with a banana, but only about one percent of total DNA matches directly.

Humans and bananas share many core genes, but only a small slice of total DNA when whole genomes are compared.

Grandparents and grandchildren share about 25% of their dna on average, though real matches usually range from 15% to 35%.

First cousins usually share around 12.5% of their DNA, but real results often range from about 7% to 14%.

Half siblings usually share about 25% of their DNA, with most pairs falling in a range of roughly 17% to 34% shared DNA.

Half-siblings usually share around 1,300–2,300 cM of DNA, averaging near 1,750 cM or about one-quarter of their autosomal DNA.

Half cousins usually share about 6% of their autosomal DNA, with real test results often falling anywhere from around 3% to just above 10%.

A grandparent and grandchild usually share about 25% of their DNA, with test results falling in a range of roughly 18% to 32%.

Gorillas share about 98% of their DNA with humans, with most differences in how genes are switched on for brain, body, and immune traits.

Full siblings share about 50% of their dna on average, though actual dna sharing can range from roughly 37% to 61% between pairs.
