Modes of Inheritance- Albinism in Snakes

[Het]

Hi All, new to the forum here, and my first post, so hope someone can answer my Question...

My Q is, What is the mode of inheritance for Albinism, is it the same for all reptiles?

I'm fairly clued up with genetics and colour inheritance with my breed of dog as i'm a breeder. I know much about the white gene, however albinism is a completely different ball park, something i'm not familar with.

With the white gene in my breed, it's recessive, so both parents need to carry it to produce it. However, depending on the colour of each parent, depends on the percentage of white puppies per litter you will get. If you breed a white with a coloured that doesn't carry the white gene, all pups will be coloured, however they will ALL then carry the white gene and produce white if mated with a white or a coloured that carries white. hahah, am i confusing you all yet? There is a lot more, but i don't want to bore you with genetic dog stuff..

Ok, anyway, could someone please explain to me, if you have a snake het for albino, will it produce albino regardless of who it's mated to? If the same pair that produced albinos were paired up again, what's the percent chance that it will again result in albinos? What is the chance percentage wise that it will produce albino ever again? How do you know which snake is het for albino, or is it like the white gene where both have to carry it to produce it? In other words, what's the mode of inheritance??

Thanking you in advance..

Albino x Albino = 100% Albinos
Albino x Het = 50% Hets & 50% Albinos
Het x Het = 25% Albinos, 50% Hets & 25% Normals
Albino x Normal = 100% Hets
Het x Normal = 50% Hets & 50% Normals

I'm pretty sure that's the go, i'm sure someone will correct me if i'm wrong.

Whilst on the subject, can anyone tell me what a "double het" is? I presume it means an animal is het for two different traits?

Thanks MB, champ!

correct

[freddy]

so if a double het is from two differant traits what offspring would you get breeding that with say a normal het or just normal? would you get albinos?

This link might help you work that out, or confuse the living hell out of you, one of the two..

what dogs do u breed ?

[Mase]

[freddy]

well then maybe i was better off asking :wink: thanks mr.B,

whats the deal with 'snow, dh sunglow, ghost and stripe'??? i understood until they come into it :roll: :wink:

[MrBredli]

Just different morphs, google them and you should be able to find some info and pics on each one.

just a cuople of questions. het do the white dogs in you breed have pink eyes or are theyjust normal white .big difference between white and albinoism as most realise .the white gene varies greatly between different animals.eg in cats the colour white masks another colour .it was explained to me as such .should you be wearing a red shirt with a white coat you are still wearing that red shirt . the white coat only covers it up .
i am only boring you with this as i have made a study of genetics in dogs birds and felines being a successful breeder of all of these at the highest level.
what het was refering to is simple recessive .and mrbredli reply is correct except het to normal wiil give 25% het and 75% normal .eg het 1st cross 50% het +50% normal mated to pure normal 100% nornal only 25% carry the het gene .don't worry only another reason to explain to the misses why you have so many

This is abit of topic but kind of related...
Are blue tree snakes a morph(not sure what is the right word)? If they are does that mean what MrBredli said about albinos would apply to them too?
