I have a pair of albino naja kaouthia which produced an entire clutch of normal babies...slightly lighter in colour but normal...can someone enlighten me on this subject?...and if i breed the offsprings what are the possibilities...thanks!!!...

It`s perfectly normal. I`m not sure about snakes but genetical mutations were off in humans after 7 generations. Stay safe...and congradulations on the clutch.

Normal X Normal = Normal - wild phenotype displayed
Albino X Normal = All offspring are 100% Heterozygous (Het) for albinism - an unexpressed gene - wild phenotype displayed
Heterozygous (like strain morph) X Heterozygous (like strain morph) =
Approximate results in clutch:
25% Albino Homozygous
25% Normal - Wild Phenotype
50% Heterozygous Albino - Wild Phenotype - gene unexpresed
The "66% het" is born.
Albino X Heterozygous (like strain morph) =
50% Albino Homozygous
50% Heterozygous for Albinism - Wild Phenotype - gene unexpressed

WOW! This sounds very interesting. OK, do I understand that BOTH parents are albino? If so, it sounds like you have a case akin to what happened in morph Burmese Python breeding.
Two albino Burmese were bred and produced all normal offspring. Basic genetics says this is impossible, but further research showed that there are two causes for albinism. And real experts can tell them apart visually.
Albino is defined as melanin deficient. Tyrosinase is an enzyme required to produce melanin. Genetically, some albinos are tyrosinase negative (T-) so they do not have the necessary enzyme to complete melanin synthesis. These are the white\yellow\orange animals with red eyes. Other albinos simply don’t have the gene to direct melanin synthesis (but still produce tyrosinase). These animals are more lavender-brown and called tyrosinase positive (T+).
Both animals are albino but when crossed the offspring have both the melanin production gene and the gene to synthesize tyrosinase (But they all have hidden recessive genes for both types of albinism). So the animals you have there are all double het for albinism. And there is no way for me to draw out a P. square for that here.
TTmm x ttMM
All offspring TtMm look normal, but the next generation will be interesting indeed!

Just to throw out another thought... Is it at all possible that the female was already gravid when you got her?

How common are Ilbino’s in the wild? Has anyone in the herp community tried to find this out, or is there any way of knowing within reason?..........Be safe ya'll, happy herping Wally

amazing!...got my doubts answered overnight....=)
phantom and super geek: thank you so much you guys!....it all makes sense now...so...according to what is explained...what i have with me is a group of Tyrosinase positive...and the desciption fits well...the group i have are lavender brownish...lighter than the normals...
LarryDFishel: no doubt about that...the albino monocled cobra pair are my second generation offspring from a pair of albinos...i brought them up and crossed them myself...
ALA_herp31: i'm not sure if they are found in the wild...but if there is, it's definitely rare...
so...now...we'll see what comes out of the cross of these offspring...they are breedable sizes now....keeping my fingers crossed....will inform you guys about the outcome....

All amelanistic snakes are albino, but not all albinos snakes are amelanistic.
Albino (T+) - 1. slang term applied collectively to identify tyrosinase +, and tyrosinase -, albinistic specimens;
2.specifically to the morphological identify animals lacking the overall EXPRESSION of melanin, but possessing tyrosinase the enzyme necessary for melanin synthesis; tyrosinase + reptiles exhibit lavendar coloration
3. Not truly amelanistic.
Amelanistic (T-) - 1. without melanin and all synthesizing components (Tyrosinase).
2. a "TRUE" albino.
Naja kaouthia, like Crotalus atrox, Python molorus bivittatus, Python regius and certainly others....are well known for their commercial morph appeal. Sometimes conflicts are reported, like the starter of this thread, reporting breeding (2) 100% Homozygous recessive snakes together resulting in completely normal looking offspring. Both of your albinos are from different strains, and their offspring are carriers of each strain. Such problems are plaging many hobbyists seeking quick returns breeding Crotalus atrox. I know of at least 4 different strains immediately in circulation. There is probably quite a few more!
Morph traits are inherited. Multiple morph traits are passed along through selective breeding and inbreeding to be exhibited in their offspring. As such is the "Sunglow Boa" (Hypo X Albino), Patternless Burmese (Patternless X Albino)., and others. Two tyrosinase + specimens (from different strains) bred together will not produce T+ albino offspring. All offspring will be double heterozygous for both T+ strains. This is why hobbyists specify the bloodlines.
