Reptile & Amphibian Forums

i just purchased a book by stefan broghammer titled Albinos (color and pattern mutations of snakes and other reptiles) im pretty sure he the guy that runs this website http://www.ms-reptilien.de/ and seems to be a pretty big breeder in the states. It has been a great book so far, and has really got me up to date on some genetics questions. As put everything out in order for me to actually understand

it does have a few things im trying to understand though, and hoping some of you guys will be able to answer my questions.

doh, i pressed enter by accident
what kind of gene is Leucisitic? the book says that leucisitic are animals where all types of pigment cells are out of function, but how do you come about this? if you had say het snakes for a out of function pigment cell? does that actually work? im very confused about it.

that said, how can we end up with a leucisitic brazilian rainbow boa? will it be one found in the wild, or will it maybe pop up in a clutch, when someone breeds the two right morphs together?

the book also shows a picture of an albino Leucistic CRB, so who ever had this snake, did they do work with it, to fiqure out the genetics behind it?

There is also a statement in the book, and im not sure if it is talking about the same CRB but it says

"Some years ago, a couple of leucistic "red" rainbow boas (epicrates cenchria) achieved that fantastic price of US$40000"

does anyone know what snakes this was, were they BRBs?

sorry for the weird questions, but im a bit fascinated by this book now, and just trying to work out in my head, where we can actually go with BRBs, ie what is actually possible

cheers

This is not a cut and dried question in this hobby any longer.

Leucism in lets say Texas Rat Snakes is a simple recessive trait, like albinism. Predictable and easy to duplicate.

In other snakes such as the newer reticulated pythons and ball pythons they are showing Leucism that is shown in the phenotype but it is NOT a simple recessive inheritance, more likely acquired through incomplete dominance or a some type of multiple gene combination of sorts, poor understood and not at all predictable as of yet in how it is occurring.

If one where procured from the wild its type of inheritance would play a part in how easy it would be to reproduce and get that phenotype in the neonates.

It would be ideal if it where like Leucism in Texas rat snakes.

But most if not all of the Leucism seen in Ball Pythons, Reticulated Pythons, and Jag Carpet Pythons are a different type of inheritance then the simple recessive one seen in Texas Rat snakes. From what I understand those Leucistic Ball Pythons are
not throwing all lucy's when bred together. So it's inheritance is not simple recessive (like texas rat snakes) it is more likely incomplete dominance or another type of inheritance involving multiple genotypes of sorts. Very confusing and interesting.

The confusion arises from labeling them Leucistic because I for one expect simple recessive deliverance like in Texas rat snakes.

They are a form of Leucism, but yet it is misleading to market them as such (IMO) due to the confusion in the type of inheritance involved and most likely expected from the buyer.

I seen a Lucy Columbian but know nothing about any Brazilians in the hobby that are being talked about.

A wild caught one with a simple recessive inheritance would be the most desirable way to get Leucism in BRB IMO.

Thanks,

I opened my mouth and out flowed a melody black.

Do you know if anyone has a pic of this Lucy Columbian?

Leucistic Colombian, at least I am pretty sure that is what it was. These PICs were going around the internet over ten years ago and had several different stories about what subspecies it was and what happened to it. You might could do a web search for the photographer and see what he knows.

I'm not much into columbians, but I always like to sneak a peak of crazy new morphs when I can

What I would like to know more about is if anyone has any info on those Albino Brazilians. I think there's quite a few of us that can't wait to see when those come out!

The phrase "two pics even" is from something in my youthful section of my mind...Tigger the tiger perhaps lol....
