Depends, if your talking about yourself, all of it.

Humans share at least some genes (DNA) with all living organisms. As far as plants, it is around 15%.
While plants and humans are very different, they do have quite a bit of DNA similarities. Humans share approximately 40-50% of DNA with cabbage. Humans share over 60% of DNA with insects, and 98% with chimps.
Humans and lemurs share about 95-99% of their DNA, indicating a relatively close genetic relationship. Despite the similarity, there are distinct differences in the genetic code that account for the unique characteristics of each species.
98%
Humans and cats share about 90% of their DNA. The genetic similarities are evident in various aspects, such as the structure and function of certain genes controlling traits like metabolism and immune response.
we share 1/3, or 25%, of a daffodil.
Humans share very little with a potato. Chromosomes are a collection of DNA woven around protein. A chromosome may contain as many as 100,000 to billions of nucleotides in one chain. Chimpanzee and humans share a very SIMILAR DNA pattern, where as a potato and a human being don't. So although they both have 48 chromosomes, their DNA STUCTURE is vastly different.
60-80%
we are all bannas and slugs and apes so they had a three way at some point
That they share a common ancestor.
