I should explain my analogy a little better.
Perhaps a family tree from my point of view would make it easier to explain (at least it would for me). And btw don't put yourself down. We are all entitled to opinions. We all as a group should stop taking this stuff personally and discuss these things in a manner thats as peaceful as the fish we discuss (thats my opinion anyway

)
Carp species
|............................. |
Koi ................Longfin sub species
| .......................................|
Kohaku Showa Sanke etc .................Kohaku Showa Sanke etc varieties
Dog species
|
Doberman ............German Sheppard.............. Poodle ..sub species
|.....................|
miniature............ full size varieties
Dogs clearly dont have the varieties that carp do but I think you get my drift. Feel free to disagree I don't mind at all. Edit- I cant seem to get the "trees" to look right. Every time I edit the formatting reverts back to something else..Sorry
