"i'm not sure if i understand what you're saying correctly. it sounds like you're saying that not all lessers carry the hidden platty gene and that the platty gene is heterozygous.

i'm not an expert but i don't think thats quite exactly how it works. i think it's a hidden co-dominant gene that when combined with the lesser platty produces the platty.

a guy i used to be friends with produced 3 platty females last year by total luck. he had a normal female that unknowingly carried the hidden gene and when he bred his lesser male to it he hit the jackpot.

here's a link to his post, unfortunately the pic isn't viewable."



Please see my correction post for what I believe to be the right percentages.



I'm saying that NO lessers can carry the hidden platy version of the same gene as lesser. Some genes only have two known versions (alleles), like stripe and normal for stripe. But for some reason it looks like this blue eyed leucistic complex gene has a bunch of versions (normal for bel, lesser/butter, mojave, phantom/mystic, Vin Russo, mocha, special, hidden, and probably others I've forgotten or that are not named yet).



I believe that the lesser phenotype is the combination of one lesser version of this gene and one normal version of this gene. If the other copy isn't the normal version then the combo isn't the lesser phenotype.



I believe that platy is the combo of one lesser version of this gene and one hidden version of this same gene. In this sense I consider platy to be a two mutant allele combo like the mojavelesser = leucistic or the lesserphantom = karma or mojavemystic = mystic potion or mojavespecial = crystal. I wouldn't really call a combo co-dominant as that term only applies to the individual versions of the gene relative to the normal version of the gene. But hard to know what classification to use for the hidden version of the blue eyed leucistic gene as it appears that even the homozygous hidden looks normal. But the hidden allele does seem to have a big effect when paired with lesser to make platy.



Your friend's hidden female could have produced platy with any lesser. A platy needs one parent to provide the lesser allele and the other parent to provide the hidden allele. So it doesn’t need the lesser providing parent to have the hidden allele too.
