Humans and zebrafish share 70 percent of the same genes and 84 percent of human genes known to be associated with human disease have a counterpart in zebrafish. Major organs and tissues are also common. Zebrafish genome has also been fully sequenced to a very high quality.
The percentage of genetic similarities between humans and animals does vary: chimps, 97% similar; cats, 90%; cows, 80%; mice, 75%; fruit flies, 60%, and jellyfish, 60%.
Now, new research from a team of international researchers shows that humans share about 70 percent of their genome with acorn worms, according to a new study published in the journal Nature.
We also share a shocking amount of DNA with plants and insects. We share 50% of our DNA with trees, 70% with slugs (gross), 44% with honey bees, and even 25% with daffodils.
You have to go much further back in the evolutionary story to find an ancestor common to both plants and animals. Humans share more than 50 percent of their genetic information with plants and animals in general. They share about 80 percent with cows, 61 percent with bugs such as fruit flies.
Explanation: Humans share approximately half of our DNA with bananas, 40% with apples, and some other species of plants are lower than that.
You may be surprised to learn that 60 percent of the DNA present in strawberries is also present in humans.
Chimpanzees are our closest relative as a species and we share at least 98% of our genome with them. Our feline friends share 90% of homologous genes with us, with dogs it is 82%, 80% with cows, 69% with rats and 67% with mice . Human and chimpanzee DNA is so similar because the two species are so closely related.
Interestingly, carrots — along with many other plants — have about 20 percent more genes than humans. This enables carrots to better thrive and develop through changing environmental conditions.
What percent of DNA do we share with dolphins? In general, however, the overall conclusion is that most genes would share about 98.5 percent similarity.
In this context, we have shown that 941 genes are shared between vertebrates and octopuses. In fact, 879 genes are shared between humans and octopuses.
For example, people and tomatoes share as much as 60 percent of the same genes.
With shared genes, we share around 99% with rats, which has been published online. With working DNA we share around 97.5% with rats and mice.
The DNA in alligators, crocodiles and gharials is about 93 percent identical across the genome. By comparison, a human shares about 93 percent of his or her DNA with a macaque. A Texas Tech University biologist led a team of more than 50 scientists who mapped the genomes of three crocodilians.
As a result, we share roughly 90 percent of our DNA with mice, dogs, cattle, and elephants.
Scientists don’t have access to DNA from any extinct dinosaurs, but they can study that of living dinosaurs (birds) and their other more distant living relatives. … We selected the genomes of certain birds, turtles and lizards and essentially did a triangulation exercise to infer the structure of long dead species.
