het percentage

[im faster]

So if u have say

Hypo het tremper

U breed it with a tremper

Does this raise the het percentage?(if u produce another hypo het tremper)

 

[Thorgecko707]

yes

 

[im faster]

To what percent is what I ment to ask

 

[Wowoklol]

Does what raise it? The het albino on the Hypo lizard opposed to Not het? No. If its not het tremper, you have 100% hets. Can't get any higher than that. You produce zero albinos. Add het albino and you get 50% albinos unless you have homozygous Hypo. Then you are back to hypos 100% het tremper.

 

[TokayKeeper]

heterozygous (for tremper albino) x homozygous recessive (tremper albino) = 1:1 ratio. Over a sample set of 1000 (1000+ would be a good sample set), statistically you should end up with 50% of offspring being heterozygous and 50% of the offspring being albino; or a percentage close to 50/50.

Statistically speaking though, each egg also has a 50/50 chance of producing either.

As wowoklol asked, what do you mean by raise?

 

[Terrain_pull up]

Forgive me trying to hijack this thread but I have a percentage question along the same lines I think.

I know if homozygote (tremper) x heterozygote (tremper) animals are bred together statistically %50 of the offspring will be homozygote and the other %50 will be heterozygote. The heterozygote offspring will be said to be %100 het tremper for example correct?

So my question is when do you get %66 het for something? I've seen this on some different websites and I'm not sure what it means. Is it when the %100 het animals are bred to another %100 het animal and then their offspring produce a normal appearing animal which would then be described as %66?

Again, sorry for the hijack...lol

Technically an animal is either heterozygous or not. The 100%, 66%, 50%, 25% het thing, to me, is more marketing than anything else. However, it does tell you some genetic history/lineage of the animal.

To get 66% hets the pairing would be a het x het breeding. From that pairing you'd get a 1:2:1 ratio of genotypes. We'll saw that this cross is a het for albino pairing. From the Punnett Square we'd in theory statistically get 4 offspring genotype combinations. 1 would be normal, 2 would be het for albino, and 1 would be albino. Phenotypically, the ratio adjusts to 3:1, 3 normals and 1 albino. Of those normals, we statistically have the chance of 2 out of 3 being het for albino. Thus there's a 66.666666666666666666666666666% chance for any of the 3 being het.

I'd explain the other crosses, but I'm not late for leaving to work....called in early sucks and it doesn't

 

[xanderville]

het Tremper X het Tremper = 66% possibility of being het Tremper (unless the offspring is homozygous for Tremper)
Het Tremper x normal = 50% possibility of being het Tremper

The 33% and 25% possible hets are kinda odd but like TokayKeeper said they seem to be more of a marketing ploy

 

[RampantReptiles]

33% and 25% is if grandparents were het... I like to include as well if I know not for a marketing ploy but just so that the buyer knows its possible they could still be het even after a couple generations.

Example... you have a 66% het Bell albino and cross it with a non het albino... you cant prove that the offspring are het or not het Bell but there is still a chance that they could be. This is VERY important for people breeding different albino types.

The more information you can provide a buyer the better. No surprises later on!

To what percent is what I ment to ask

Tremper X hypo het Tremper = Trempers and 100% het Trempers

Great explanation. Thanks!

Actually you get this via breeding the possible het to a normal.

A 66% possible het X normal could in theory be either all normals or 50/50 hets/normals, but because you have a 50% chance of the offpsring being hets you would then divide the parent's percentage by 2. Thus all offspring from a 66% possible het x normal pairing would be 33% possible hets.

The same applies to 50% hets...crossing into a normal would result in 50% chance of offspring being het, divide by 2, and you get 25% possible hets.

 

[RampantReptiles]

Example... you have a 66% het Bell albino and cross it with a non het albino...

66% het Bell... parents 100% het Bell
crossed with non albino or het albino aka a normal

66% het Bell X non albino = 33% het Bell
OR
Grandparents were hets

Just another way of looking at it.

 

[lillith]

I always thought it was viewed as responsible to disclose the percentage of possible hets to potential buyers...so are you saying it's negative to say anything other than "possible het"? I mean, if I were going to buy a possible het - trying to breed for the trait the percentage was given for - I would choose a 66% or 50% het chance, over a 33% or 25% het chance...does that make sense?
