Genetics questions you were afraid to ask...

Well it looks like I may be getting some Plasma and Hypo Plasma corns at the september hamm show.....I will be reserving them this week.

What are other morphs I can put too the plasma's to maybe get something interesting?????

Hi just about to introduce a female hypo jungle to my mack snow pastel. What are the possible outcomes?? Also if my female high yellow is ready in time what would be the outcome of her and the pastel??

Any help would be apprectiated
Cheers

Plasmas are lavender bloods so basically anything you'd like a mix of - lavenders always look good mixed with hypo or patterns - mot/stripe and bloods make amazing combinations with practically any morph.

Advice needed Guys. From a beginner!

If I buy a 100% Het Albino Royal (Male). Is he only 100% het albino because he has sired some albino offspring? If so and I put him with a 100% het female how would I know if the offspring were hets or would i only now after breeding?

Thanks

100% het *could* be because he's fathered albinos, although then he'd probably have had 'proven' added to his description by whoever's selling him, so it's more likely that it's because one of his parents was a visual albino.

two 100% het albino royals mated together gives each egg -

25% chance of being normal
50% chance of being het albino
25% chance of being visual albino

there's no way of telling hets and normals apart (other than growing them up and test mating them!) so the visually normal offspring would all be classed as 66% poss. het.

Is it a Mack Snow or is it a Mack Pastel? These are two totally different genes - related, discovered by the same person, but they don't work the same way. A Mack Snow bred to your Hypo will make some normals, some hypos, some mack snows and some hypo mack snows. A Mack Pastel bred to your hypo would produce some normals, some hypos, some Mack Pastels and some Hypo Mack Pastels. The difference comes when you breed a mack Pastel to a mack Snow - you will NEVER get Super Snows out of this combination (and there's no "Super Pastel" either).

Your high yellow will produce normal/high yellows and Mack whatever-yours-is.

It is a mack snow pastel. Thanks for putting it bluntly for me I have been looking into it and the further I got into looking the more confused I got myself due to the mack snow pastel being a dominant gene.
Cheers anyway

Is it a Mack Snow (that's the codominant gene that makes Super Snows in a double dose) or a Mack Pastel (that's the dominant gene that doesn't have a super) ?

Calling it a "Mack Snow Pastel" implies it is both a Mack Snow AND a Mack Pastel... which I have never heard of though I cannot imagine it's "impossible".

Hi guys

I am toying with the idea of possibly breeding Royal Pythons.
I currently have a normal 06 male and it wont be for a good while yet but can anyone explain how dominant, recessive genes etc work. Someone tried to explain but made a mish mash of it and now i'm really confused.

For example if i was to breed my normal male with: -
a mojave,
a albino,
a spider

or any of the above as hets (normal with mojave het) what would the out come be. It is much different to corn breeding it seems.

Thanks for any help.

Ok.

In Royal Pythons, albino is a recessive. This means that one copy of the Albino gene (plus one copy of "not albino") looks exactly the same as no copies of the Albino gene. It takes having two copies of Albino to look visually albino. If you bred your normal male to an Albino female you would get all normal-looking offspring who are het for the albino gene. If you bred your normal male to a het albino female, you'd get all normal-looking offspring who MIGHT carry the albino gene - but there's no way to tell visually.

Now, so far, Spider appears to be dominant. This means that one copy of the Spider gene (plus one copy of "not spider") looks exactly the same as TWO copies of the Spider gene. There's no way to tell visually whether you have a one-copy heterozygous spider or a two-copy homozygous spider - but if it doesn't LOOK like a spider it doesn't carry the gene at all - there is no "invisible het". If you bred your normal male to a Spider female you'd reasonably expect at least some Spiders in the first generation; if you ever got a normal offspring, you know that your Spider female is a "het" Spider - she only carries one copy of the gene, and also carries one copy of the normal not-spider gene.

Mojave is a co/incomplete dominant gene. This means there's three distinct "looks" - if it's got no copies of Mojave, it is normal; if it has one copy of Mojave (AKA het Mojave) it is a visual Mojave, and an animal who has two copies of Mojave is a Super Mojave - a visually white/pale snake with a sort of smudgy pattern on the head. If it doesn't look like a Mojave or a Super Mojave it doesn't carry the Mojave gene at all - there is no "invisible het". If you bred your normal male to a Mojave female, you'd reasonably expect some Mojaves in the first generation; if you bred your normal male to a Super Mojave female, you would get all Mojave offspring in the first generation.
