Humans share around 80 to 90 percent of their genes with mice, depending on how similarity is measured.

Monkeys and humans share roughly 93–99% of their DNA, with chimpanzees closest and Old World monkeys such as macaques still sharing about 93%.

Humans share about 60% of their genes and around three quarters of disease-related genes with fruit flies through shared evolutionary history.

Pigs and humans share most of the same genes, with roughly 98 percent of human genes having a counterpart in the pig genome.

Orangutans share around 96–97% of their dna with humans, depending on how scientists compare the genomes.

Humans share around 90 percent of homologous genes with cats, meaning our genomes carry a closely related mammal toolkit under the surface.

Humans likely share roughly 80% or more of their DNA with dolphins, depending on how scientists compare the two genomes.

Monkeys share over 90% of their DNA with humans, while chimpanzees, our closest primate relatives, match about 98–99% of our genome.

Humans and dogs share roughly 80–84 percent of their DNA sequence, reflecting a long history of shared evolution and companionship.

Full siblings share about 50 percent of their dna on average, with real results usually landing between roughly 38 and 61 percent.
