What Nick said.

Also take a look at our FAQ entitled, 7. What does heterozygous, homozygous, recessive, co-dominant and dominant mean?

Thank you both!

Hey guys, I was reading up on a website, and the author stated that, for example, a spider snake can be het for normal? Thus producing a different outcome in the punnet square. They also said an albino can be like this as well, this het for normal. They called them visual albinos and true albinos. I don't understand, I thought an albino was an albino

[BP_Lover]

what would happen if you breed a normal to a spider?? and i know this probably seems dum what what is a normal a dom or codom and alos what about a spider same question thanks

[NickMyers03]

spider is a Dom as there is no proven super. there has thought to be some made but its a leathal gene. there is one person i know has had 4 clutchs of spiders from the same male that came from a spider to spider breeding and EVERY offspring has been spider, BUT more than have the babies have been dead in the egg.

i guess you could call a wild type or normal a Dom as it will show up 50% of the time or at least be 50% of the genes because it has no normal. if Ron wants to chime in on the normal genes please do i have never thought about it LOL

Spider X Normal =

50% Spiders
50% Normals

[BP_Lover]

so then the whole punette square doesn't apply because Spider (A,A) and Normal (B,B) would make them all 100% het for spider im confused this is what i read ( well understood from a website deb told me about)

Spider is not AA because it has half normal Gene so it would be A a

Normal also isnt NN its N n.

so you would get a split of 50% spiders and 50% normals if odds where exact. now you could also have the odds against you like i just did on my pastel clutch and get 2 pastels and 4 normals...

the only way you would get 100% morphs in a clutch is if you have the super form of that morph ( example= Blue eye lucy, Ivory, Super pastel, super cinny/black pastel and so on)

There are a lot of misconceptions and bits of misinformation posted on the internet...that should be common knowledge. Factor in something that is not generally well understood by most people, and you can increase the number of errors significantly. I don't claim to be a genetics whiz, but trying to blindly put letters into a Punnett square without understanding the way the genes work doesn't always give the best answers (and the answers don't always make sense).

Not to pick on Nick, but his statement that normal isn't NN, its Nn, just strikes me funny. I think that people would be better served trying to comprehend the basics than battling over the labels. Let me put it in a different perspective. Tradition would dictate that a homozygous albino is AA, and a het is Aa. What if we said that the het is Na (normal, het albino). and a homozygous albino (by necessity) is aa.
breeding a het x a het would still give you NN, Na, Na, aa; wouldn't it?
and a homozygous x a het would still be aa, aa, Na, Na; right?

To take it a bit further along this path, consider a spider to be Ns
a spider x a normal would still be Ns, Ns, NN, NN. which makes as much sense to me as calling it Ss and getting NS, NS, Ns, Ns (with the NS being spiders, and the Ns being normals).

Learn...don't just apply

[NickMyers03]

harald you just said what i said more in depth... you can replace the NN with anything you want...make it XX or xx or Xx if you want it still comes out the same..

but the examples you showed still were correct as a het to het breeding will give you the chance of 25% of the babies being albino

and spider to normal still came out as 50% split


NOW........ on the subject of a visual albino or true albino...this person that said that ( if they really said that which i think any one that knows bps as you said they did wouldnt ) is STUPID... an ALBINO is an ALBINO. your trying to state there are Albinos and snakes that look like ALBINOS... stop listening to this person and if he tries to talk to you RUN.

there are diffrent types of albinos, blusher,HC,fader and so on but they are all ALBINOS...
