Can any breeders that have bred GFP axolotls tell me what their offsprings expressed? Did two GFP parents produce 100% GFP or less? I've been finding mixed results on this because GFP doesn't act like the normal set of genes. Just want to get an idea because I may try breeding my GFP male with my GFP female.

Axolotls are illegal in California. Please read this thread for detailed information and links to the actual laws: https://www.caudata.org/threads/axolotls-are-illegal-in-california-here-are-the-relevant-laws.30779/

From what I've read GFP genetics is fairly simple as it's a yes-or-no gene. It can be passed on from either parent, you don't need a pair of genes like you do with albinos.
So if one parent was GFP about half the offspring would be too, if both parents are GFP about 75% will be GFP.

Yes, but it makes no difference - it's a yes-or-no gene. Doesn't matter whether it gets a yes from one parent or both!

I don't think so. The gene is a recipe for the GFP protein, it tells the axie how to make the protein not how much to make!

GFP works as a dominant gene. A particular animal expressing the GFP trait may be either heterozygous or homozygous. 50% of the offspring from a heterozygous individual will express the trait, while all of the offspring from a homozygous individual will. It's pretty easy to grasp once you know that much.
Ah I think my original intent might have been lost. I meant more along the lines does the gfp gene act like simple dominant/recessive inheritance or does it have varying levels of expression between homozygous vs heterozygous individuals. I believe now it's just simple on/off, have it or don't. Thank you everyone for the replies!

There is a school of thought that suggests the gfp is expressed more strongly in individuals with two copies of the gene rather than one.
I lean toward believing that may be true, based on the gfp spawns I've raised so far. I can't prove it, obviously, but something's making a large percentage of my gfp juveniles (from two gfp parents) glow more strongly than the others in the same spawn.

Shane douglas:with axolotls would I basically have to keep buying and buying new axolotls to prevent inbred breeding which costs a lot of money??+1

Thorninmyside:Not necessarily but if you’re wanting to continue to grow your breeding capacity then yes. Breeding axolotls isn’t a cheap hobby nor is it a get rich quick scheme. It costs a lot of money and time and deditcation+1

Clareclare:Would Chinese fire belly newts be more or less inclined towards an aquatic eft set up versus Japanese . I'm raising them and have abandoned the terrarium at about 5 months old and switched to the aquatic setups you describe. I'm wondering if I could do this as soon as they morph?+1
