I know that doesnt say its not genetic, but it explains why. But the second quote says its not genetic. Its the same as humans, and I think that has been proven not to be genetic, I may be wrong though.

No, it doesnt say why it isnt genetic - it just states one of the reasons it happens. There are many different stages of severity each one is caused by a different reaction at a different time during incubation.

No idea when it comes to human form but i would guess that any offspring would have a higher likely hood of being the same, which i suppose means it is genetic. So i do have an idea Embarassed

Can you post the other quote up Smile

A nice looking snake but did anyone notice that ' It is currently at the prime age for breeding and is expected to live for another 10 to 15 years. '

The world aquarium bought it at 6 1/2 years old, has had it for 6 years. That makes it 12 1/2 years old which is a good age for a rat snake but hardly 'prime breeding age' and doubtful if it would live for another 10 - 15 years.

A not very well thought out selling ploy ?????

I know what your saying there, but its worth thinking about average "litter" size for humans. Beating the odds isnt hard to do when you only have one offspring at a time.

I personally don't know of any human siamese twins that have only been joined in the neck area (one that was at the top of the head) and i don't know of any instances in reptiles where it has happened in any other area but the neck/head.

I also know of a case in beardies, so is that the same?

I would imagine that's why no one has said either yes it is genetic or no it isnt. To do it on a genetic level would be very hard i'd think, first you'd have to find the "coding error" that caused it!! Then you have to find out if the cause is the same in snakes as it is in humans.

Then you have to ensure it is either all caused by genetic mistakes or all caused by some form of physical anomally (ie temp during incubation). But if it is caused by both you would then have to distinguish from the 2 and follow each one.

This is getting way beyond my understanding now and i am likely to lose myself shortly Embarassed

I am just gonna stop here with saying siamese twins in reptiles may be a genetic trait but it will be far more complex than a simple recessive gene. Very Happy

Not particularly a nice sight, but here are siamese dwarf burmese babies from last week. Fortunately, due to the severity of the deformity they/ it did not survive.

producing Het albinos not enough for you??? you have to try for siamese twins too?

Peter, any chance you can post photos up for our forum members of the dwarf burmese and some size info about them?
