gentics ?!?!?!?!

MatNga Jul 05, 2003 12:54 PM

hey guys i have question this 100% het stuff. What does it mean?!?!

i mean i see people saying that they have 100% het for albino. does that mean that the lizzards being bred both male and female where albino and it came out normal? if two albinos are bred togther would the offspring be 100% het for albino?

and what about pattenless 50% het patternelss

if someone can explain this to me or point ot the information so that i can read it myself would be great. i understand genitics pretty well in humans and plants ect i think the piece of leo genticsi am missing is nomenclature in what is RR and what is Dom.

100% het for albino would mean that the parents are one albino and one normal. a 50% het for patternless would mean the parents are one het for patternless and one normal. the 50% is because out of that crossing, 50% of the babies will be hets, and 50% will be normal. since you can't tell be looking, they call all the babies 50% possible hets. an albino crossed with an albino results in all albinos, assuming they are the same strain of albino.

in 100% het baby the normal would have to have been from an albino breading though right? because if you take a normal not knowing whether or not it has a gene for albinoism ( i assume albinoism is RR in loes) and get no albino babies than you wouldn't have 100% het baby. the only way to know if a baby is 100% het is if an albino was bred to a naormal and in the cluch there where albino babies right ?

this doesn't seems very scientific to me if your just lookin at one and since you can;t tell you mark it 50%

i dont really understand what your saying, but i'll try. if you breed an albino to a normal, you cannot get any albinos. but ALL the babies will be het for albinism. its not too complicated.

>>this doesn't seems very scientific to me if your just lookin at one and since you can;t tell you mark it 50%

it isnt scientific, its mathematical. when u breed a het to a normal, 50% will inherit the gene, and 50% wont. since you can't tell from looking, you label them 50% possible hets, because they all have a 50% chance of being a het. if you breed a 50% het to lets say a 100% het, and get albinos, the 50% het is now proved to be 100% het.

if you have albino male and one female het for albino (normal color) you can get albino babies right?

however for that to happen you would have to have bred an albino x normal and got a het for albinoism in the normal color leo. now if you breed two 100% het for albino leos togther you should be able to get an albino hatchling since they both are "100% het for albino" meaning both carry the RR gene for albinoism

is this right ?

>>if you have albino male and one female het for albino (normal color) you can get albino babies right?

out of this crossing you will get about 50% albinos, and 50% hets.

>>however for that to happen you would have to have bred an albino x normal and got a het for albinoism in the normal color leo. now if you breed two 100% het for albino leos togther you should be able to get an albino hatchling since they both are "100% het for albino" meaning both carry the RR gene for albinoism.

2 100% hets breed together should give you about 25% albino, 50% het for albino, and 25% normal. all normal looking offspring are considered 66% het for albino until proven.

i got it now thanks.

this is one thing i don;t understand yet though

you breed a het x het and get
25% homozygos
25% normal
50% het

why do breeders say 100% het

MatNga Jul 05, 2003 06:16 PM

i think i just firgured it

you can call a het 100% when it is bred and produces an albino ?

Josh06 Jul 05, 2003 06:54 PM

Yes, if a possible het.(66%,50%, etc.) is bred and the recessive gene is shown physically in the offspring, then the possible het. is proven as a 100% het.
