Question: Golden Albino x Albino

[araceae]

I have 3 golden albino axies that have been shooting out eggs like crazy.

I recently received a few normal white albinos. If the two are crossed what would the outcome be? I was thinking it would just be Golden albinos and Albinos, mosly normal albinos. (golden is recessive?)

Golden is actually dominant.

It depends on what genes the parents are carrying. If the golden is recessive for white albino, you'll get 50% golden, 50% white. If the golden is not carrying the albino gene, you'll get 100% goldens.

And if the parents are carrying other underlying genes (Melanoid, axanthic), you could get some of those in the mix.

Expanding on Kaysie's explanation albino is actually the recessive gene which if two copies are present prevents the formation of melanin, the brown/black pigment. Golden albinos have two copies of this gene but still have the ability to make the yellow and shiny pigments.

White albinos (genuine pink eyed ones) have some other recessive gene in addition, either a pigment distribution gene (Leucistic) or melanoid or axanthic which stops or reduces the expression of yellow pigmentation.

If you cross golden albinos with white albinos all the offspring will be some sort of albino and about half will be golden. All may be golden if the goldens do not carry one copy of another recessive gene.

You will not get dark melanoids or wild types from this sort of cross.

I'm not sure what you mean by normal white albinos. If you meant the black eyed leucistic axolotls then if crossed with a golden albino in the first generation offspring you may get 100% wild types if they do not carry other recessive genes and various other mixtures of offspring if they and the goldens have other recessive genes.
