Genetics question...

[NYCSpeedcore]

I am a little confused on a few things if anyone can help shed some light on the mater. If I buy a 66% het female and a 66% het male for albino when breed together should I get some albino's? I was not sure if the percentage means they may be a het, or that they will produce that percentage of babies with the trait. My next question is that if I do understand what is going on, a 100% het breed to a 66% het should produce 6.6 babies out of 10 babies with that trait visable, is that right?

	Heterozygous Heterozygous - the animal carries the gene for a genetic trait but does not outwardly demonstrate the trait. Example: A boa that is het for albino looks normal but carries the albino gene. When it is bred to another het for albino boa or an albino boa, a percentage of the offspring will be albino.

tween you and me, and every one else here- i would never buy a 66% het for anything unless its at a normal or near normal price!

reason why, people lie. i can tell you i have 66% het for anything i want, charge what ever i want- when you grow it out and breed it, and its nothing- hey, you had a 66% shot and didnt make it.

thats all 66% means. it may or may not carry the gene. you have a 66% chance of it being. you may be lucky, or if your like me, you wont be [img]modules/Forum/images/smiles/icon_eek.gif[/img]

also, the guy MUST be able to prove the genetics for you.

my opinion. be careful.

the percentages are in referrence to the potential of being het for a trait. 66% hets come from a het x het breeding. Two out of every three normal looking babies should be het for the trait. You are gambling on wether or not the animal in question contains the het gene. It would look lik this (sorry for the crudness):
B = Normal
A = desired trait

BA

BA BB BA
AB AA

One would display the trait, and three would not (assuming this is a dom desired trait). Of the three that dont display the trait, two are hets for the trait, and one is not. Hence 2 out of three, or 66% chance of het.

If I am wrong, Please delete this.

Here is a better representation:

BA
BA

breed together would equal four genetic possibilities:

BB
BA
AB
AA

AA is dom desired trait.

no that 66% het is a crock unless you buy from someone you trust. Like CB said I can say anything to get you to buy. a het-het breeding should bring in 25% albino stat wise. Not always the case though. I have seen them only bring in 10% of albinos. It is all playing the odds. pay the extra money and get 100% hets from a repetuable breeder.

Ok, then the only way to know you are going to know that the trait will be passed on is to get two 100% hets. I sort of had the impression that a 66% het would produce young in that ratio, not the possibility of it carrying that trait. Thanks for the help guys.

CB is right ... I believe we had this disscussion on another forum once.

50%,66% just means that you bred a combination and there are normals and hets left.
scientifically 50%,66% of the litter should be het for the trait.. So the one you buy could or could not have the trait. I also aggree with Jolt. If you are looking to start up something .. buy the sure thing or else you will put in like 2-3 years work only to get let down when all you babies come out normal looking.

Its like playing the lottery. Some times you win sometimes you dont.

good luck!

I am new to this too and have a similar question. If you breed two 100% Hets do you get your desired trait? Or do you have to have one 100% Het and one that is the trait you are breeding for. Thanks so much you guys are great with answering questions.

when u bred two 100% het you should
scientificly get 25% of the babys albino (or whatever they are het for)
50% het albino's and 50% normals.. but u cant tell which are the hets from the litter and which are the normals.. so u call all the normal looking ones 66% het albino.
if u breed a het to a albino,you should get 50% albino's and 50% hets,
but u can get diffrent percentages,you could get 75% albinos,and 25% hets
or 5% albinos and 95% hets... but scientifictly u should get around the range.

that should actually be 25% albino, 50% het and 25% normal

ya.. typo .. lol
25% albinos 50% het and 50% normaL?? hehehe

I have come to the conclusion that I would never purchase anything but a 100% het, and that would be only from certain people... ones that I know I CAN FIND in three years if I find out it's not a 100% het...

I tend to agree with everyone. I have a few 100% hets and 1 66% the only reason I got it was I wanted an anery and this one happen to be a 66% and the price was only 20 more. Unfortunatly hets are always iffy but with the prices of some morps they are the best way to get in to them and not pay the hight price.

I kinda disagree on the het thing. I do agree that you should buy them from someone that you can trust, but percent hets are a great way for someone with not a lot of cash to get in on breeding morphs. Most percent chance hets can be found for very close to what a normal would cost and far less than what a 100% het would cost.
Example: I bought two sexual pairs of poss DH for snow boas for much less than what a 100% pair of hets would cost me. For someone without the $2000-$3000 dollars for 100% DH snow boas (which was the going price at the time of purchase) this was my only oportunity to get into that.
You should DEFINATLY be careful who you buy from b/c there are people like Jesse Underhill out there that are looking to take your money on hets that are het for nothing. However, there are ways of verifying genetics. Make sure you see pics of the parents, ask them where they got the parents and verify that with the breeder they got them from (if this is possible an that person is reputable). If you are going to buy poss hets you MUST be very picky, but for those without tons of scratch it is an option to get into the morph you want.

Just my .02 cents worth...[img]modules/Forum/images/smiles/icon_smile.gif[/img]

	Morph A morph is a color or pattern variation that is proven to be genetic. Common morphs include albino, anerythristic, gentically striped, Hypomelanistic, and many others. Morphs also include combinations of simple traits such as "Sunglow" which is Albino and Hypomelanistic. These traits may be recessive traits, co-dominant traits, dominant traits, or created through selective breeding (ie Pastel).
