Humans share about 70-75% of their DNA with snails. This similarity is due to shared genetic sequences that have been conserved over evolutionary time.

Humans share at least some genes (DNA) with all living organisms. As far as plants, it is around 15%.

Humans and dogs only share about 25% of the exact same DNA or genome sequence. They also have a different number of chromosomes. Humans have 23 pairs of chromosomes and dogs have 39 pairs.
You probably share about 50% of your DNA with a sibling. Theoretically, it could be as low as 0 (though that is extremely unlikely). Identically twins share 100%. You always share close to 50% with each parent. But if you are male, you actually have a slightly higher percentage from your mother (because the X chromosome is larger than the Y).
Not much- probably only about 25-30%.
