Co-dominance incomplete dominance.

[soad]

I'm a little confused on this. After reading Vincent Russo's explanation it makes it seem that most traits known to be co-dominant are actually incomplete dominance. Can anyone clear this up a bit for me? Basically anything with a super form should be an incomplete dominant trait right?

Don't worry you are not alone. For the most part the two terms are basically the same but used interchangeably. And you are correct. Co Dom is a visible mutation when a single gene at a allele is different than normal. A matched pair of this gene brings on a "super" form that looks different than the single. A allele is one member of a pair of genes at the same locus or location. The locus is the location of a gene / allele on the dna strand.

Short answer is yes.

An animal that has 2 copies of the incomplete dominant gene (co dom) is a super. Instead of passing the gene to 50% of the offspring it Will pass on one copy of the gene to ALL offspring because it has 2 copies of the gene instead of one.

Think of it as doubling up when it's a super.

In ball pythons some incomplete dominant genes are compatible with one another meaning you can produce the super without doubling the same gene (alleles)

For example: Mojave and lesser are part of the BEL complex meaning

Mojave x mojave will give you BELs
lesser x lesser will give you BELs
Mojave x lesser will give you BELs

The difference is in the breeding potential of the 3 different BELs.

The super Mojave (mojo x mojo) will produce a clutch of mojos

The super lesser (lesser x lesser) will produce a clutch of lessers

But the lesser mojo BEL will give you 50-50 lessers and mojos.

I know it was a ball python example but I hope it cleared it up for you!

Wrong!

Incomplete dominance and co-dom are not "basically" the same. May be used to describe morphs but doesn't make them the same. People simply use co-dom in correctly.

I always ask for sources so here's a good and easy to follow one. I'm simply too lazy to type out.

Thanks for the clarification...

That's an interesting way to put it. I think co dom works better to describe pairings that are allelic instead of being a catch all for all incomplete dominant genes.

Thanks everyone for the help! It is much less confusing now! That link was a big help.
