If you inject a color, the offspring will not have that color.

If I cut off your leg, would your offspring have only one leg?

And wouldn't people inherit tattoos?

There's a chance...:lipssealedsmilie:

You are effecting the physical body not the inherited traits within DNA.

That is exactly the point I am making.
There is no dying/dye injection involved.
This is accomplished with a plasmid in a protein shell mimicking a viral infection to reverse-transcript the genome of the entire organism.

I think they were injected, and now bred that way.

That wouldn't work. You have to change the DNA to get an inherited characteristic. Lamarck got it wrong . Injecting something into a fish does not change the fish's DNA, and therefore will not produce an inherited characteristic.

GloFish were injected with a Jellyfish Gene that made them glow, they bred and their offspring were glowing too...

Not quite. The embryos had the gene implanted into the actual DNA. You couldn't achieve this by injecting in the conventional manner into an adult organism.

Very good point.

exactly. they are an example of a transgenic organism.
