Exactly my point, my following discussion is Phenotype only and the genes that go into them.



Co-dominant is where there are three visibly distinguishable phenotypes AA Aa and aa where A is a the dominant gene and a is the recessive gene. In Motley for example:



MM, two dominant Motley genes = purple patternless

Mm, one each dominant motley and normal gene = Motley

mm, two normal genes = normal





Dominant is where there are only two fully distinguishable phenotypes. NN and Nn are one phenotype while nn is the second.

In Salmon/Hypo for example



SS, two salmon genes = Salmon (while there are some markers that help pick out some of these, it is not 100% reliable as in Motley)

Ss, one each Salmon and normal gene = Salmon Many look just like the homozygous animals

ss, two normal genes = normal



Similar results for recessive traits Except, the phenotypes are switched since the Normal gene is dominant over the morph gene.



For example Albino,

AA, two normal genes (note they are capitilized since they are dominant) = normal

Aa, one each normal and albino gene = normal

aa, two albino genes = albino





The bottom line why Salmon is currently classified as Dominant is the Heterozygous animals cannot be 100% visually identified from the Homozygous ones. Yes, you can pick out some with a very high probability but you cannot for example take an entire litter of 50/50 het/homozygous animals and divide it into two distinct het and homozygous groups. That's why you see probable super, and possible super. Those that have the "look" little to no black around the tail blotches are probables, the rest are possibles. Maybe even those that really don't look it at all are marketed as salmons.



Super salmon is a slang term to describe a homozygous salmon. so a "super" salmon would pass the trait on to ALL of it's offspring.



>>so, the hypo/salmon gene is just "dominant"!? If it was a simple dominant then an animal would either be hypo/salmon, or not. And it would either pass it on, or not. There would be no such thing as a "super salmon" with extra markers (more reduced pattern) than a regular salmon. An animal that is hypo/salmon WILL show it. Cannot hide. that makes it appear to be a "dominant" trait. But in reality, it is more like a co-dominant... Genetic inheritance of co-dominant genes works in essentially the same manner as genetic inheritance in simple recessive genes, except for the fact that heterozygous animals are visibly different than normals. These visible "hets" can be bred together to produce an even more extreme variation of the mutation, often called a "Super." The "Super" is a dominant form of a co-dominant gene, and can be bred to a normal animal to produce entire clutches of the visible het, or co-dominant form. Examples of co-dominant traits are arabesque, hypomelanistic, salmon, jungle, motley, and pastel.
