Answer 1

Nope. Symbiosis is a close ecological relationship between the individuals of two (or more) different species. That means that each part in a symbiotic organism has different DNA.

We do have symbiotic relationships with the bacteria in our gut that helps us digest our food. But the bacteria is not us.

;-D All our parts come from the same DNA.

Answer 2

I think you are thing of symbiogenesis which is a widely accepted theory put forth by Lynn Margulies and Dorian Sagan. This elegant theory states that humans are the complex, sophisticated. animals we are because we are a collection of cooperative organisms.
At some points in our prehistoric evolution we imprisoned or were "infected" by other organisms (bacteria for instance) which we developed a symbiotic relationship with and eventually we and the organism became inseparable.
Perhaps the best argument for symbiogenisis is our own mitochondria, which have their own DNA and while they function to provide energy for our bodies they seem to have a life all of their own.

Answer 3

My body came into existence by the symbiotic influence of my mom and dad, which is a vision I don't even care to think about.

Answer 4

No
