In regards to this comment: The inability to produce offspring from this mating is purely environmental . I would suggest that perhaps the sex ration difference that you mentioned could also relate to temperature during inqubation as this is known to affect some amphibians and reptiles….. If this was a sex linked mutation ( which it is not) then you would only breed females as the males would be `Heterozygous` known as `split` for the mutation. However even this mating if this was a sex linked mutation would still produce one in four …. SEXLINKED INHERTANCE Normal /split INO X Normal Female = 25 % INO Females 25% Normal Females 25 % Normal Males 25 % Normal /INO Males This is a percentage out of approximately 100 animals , not necessarily from the same pair but from the mathematical genetic equation . In my case I produced over 10,000 tadpoles from four separate mating’s , of these supposed splits . To date I have not produced any colored tadpoles. Until you have produced large numbers of progeny to back up what you are saying , then one is flying in the dark. I have over 25 Years of breeding both bird and reptile mutations in four countries , in a professional capacity ….. So you will understand my disappointment in relation to this matter.

There is nothing complex about this mutation.... If records are kept ..... Lutino Bell frogs have accured in two locations in NZ, Auckland and Dargiville

I have mated four trios of your ”Guaranteed Splits” resulting in over 10,000 tadpoles from the frogs purchased from you. I have not had a single colored tadpole…. I also know of one other person who had some of your “Guaranteed Splits”!!!!! Who is also, yet to breed a colored tadpole. To date all known Albino and Lutino mutations in amphibians and reptiles is `SIMPLE RESESSIVE`, there is nothing complex about these mutations to those who have been for a doing it a long time…

What did you get from split to split ?

If Split x Split (of a recessive mutation) are not producing coloured progeny then your origional breeding stock can not be split, You perhaps have split to normal ??? Simple recessive, must resoult in 25 % coloured, 50% Normal split, and 25 % Normal of either sex. According to all international breeding resoults of mutations in Reptiles and Anphibians .... The only way to tell a split from a normal from this mating (as above) is to test mate it back to a coloured of the same mutation...

Yes but Leucistic is not Lutinoistic, the former is known as a dark eyes clear, such as in the case of `white walking fish`

I kept Reptile s in Canada for several years.

To make an albino anything you need to remove both yellow and blue http://www.awsaclub.com/healthgenetics/ ... entics.htm Here is a link to The Theories Of Genetics there are only three modes of transfurance they are recessive, dominant, and sex linked..... All knowen mutations, through out the animal kingdom fall under one these linkages... If not then it is an aquired colour (not a mutation) or a sport (not capable of reproducing the gene)

no

Green is made up of Blue and Yellow which gives the `visual elusion of green` …. If you genetically remove Blue , as may be the case of these frogs you are left with Lutino…. ( Which is comprised of the `INO’ Gene + Green ) …. In order to breed Albinos you need to need to Genetically remove both the Green and the Blue which leaves nothing …. Ino + Nothing + Nothing Leaves you INO… In Latin we would refer to Albino as `Alba` or white.

Interesting that these are referred to as Albino, as in order for them to be albino you would need to have blue? I would say they are lutino !
