leucistic?

[Jakub Urbanski]

Ceratophrys cranwelli SNOW! Two recessive traits (albino and leucistic?) in one frog with the translucent skin... Second picture shows final stage of the 'bleaching'. Within a week or so from the tail loss, they loose all traces of the yellow pigmentation... Out of some 900 albino froglets just a dozen or so look like this...

These are a type of albino. They fully lack melanin (the red eyes)

I have no idea what it is but it looks very cool!

they also lack yellow pigment. It is yet another recessive trait, unrealated to albinism. Out of 3 pairs of albino we bred recently only one produced that kind of offspring. Shortly after metamorphosis they look like regular albino, and soon afterwards they "bleach". The one with yellow patch on the back is already white, by now...

[Jakub Urbanski]

it is, Carole! doesn't it? We were very excited to find them among the herd of albino froglets...

What type of albinos were bred? Any samurai

[Jakub Urbanski]

Nope. You can see the pics of amplexus here: https://www.facebook.com/photo.php?f...type=3&theater

These are so cool looking!

Hello and welcome to FF Jakub! Not leucistic since those lack all colors on organisms body and have normal colored eyes. Appears more like a translucent effect of sorts. Visited your FB pics page and saw many very nice frogs there, congrats !

Thanks! We will keep updating the gallery...

I know that leucistic have normal colored eyes, but please keep in mind that those are also albino. So they are bearers of the two recessive traits. It is the same with leopard geckos - true leucistic are black-eyed, but so-called supermorphs (two recessive traits or more) leucistic/albino are red-eyed.

We call them white albinos. There is a few here in the USA and the rest are in japan. Mutant morphs help produce frogs like this. Your female seems to be of the lime green albino type.

i have blue eyed leucistic, translucent and frogs with transparent skin.

If yours came out one color and started changing colors they are mutants.

Thanks Mike! Do you have any experience with breeding them? And genetics behind that trait? In my opinion it is reccessive mutation, my guess would be that more than a single allele is involved (judging by the frequency) or it is de novo mutation (unlikely, as there are more frogs with the same phentotype, and if it shows up out of sudden it must be dominant). Also interesting is that those frogs emerged as the very last from the whole batch, kind of retarded... It took them some 2,5-3 weeks longer than average... We are going to breed this pair once again in a month or so, and will see if we get more frogs like this...

Most mutant type pacman frogs are the last to come out of the water. See if the back half of the belly is clear on those frogs. As far as breeding those babies back to each other you may not get the same colors as the parents.

my two phantoms here do not produce phantom when bred together.

So even with line breeding say 3 or four generations you still ca b there predict if not all a majority of your spawn.

You have to line breed for many generations it seems to focus on producing only one specific color per spawn

[Jakub Urbanski]

Well, that is what we are planning to do hopefully all "whites" will reach adulthood.

Thanks for the tip Mike! We still have some 30+ "late" tadpoles - and most of them look kind of strange...

Interesting, these results are similar to some fish genetics, where breeding a male and female with variation does not produce the variation (i.e. an Electric Blue Jack Dempsey).

I never thought to compare it to fish as many chiclids as I bred
