100% Het ? I am lost

[erinherington]

I am just now getting into breeding and am confused. 100% and 50% and I can't find a calculator that will (or that I can figure out how to) put in the percentage. If you breed a 100% het albino to a norm will you any albino's? If you breed a 100% het albino or pied to a spider will you get any of the albino or pied geene? Please help I am lost.

On world of bp's calculator the het pied/albino/any other recessive morp means 100% het. If an animal is 50% or 66% het then that means you have to breed them to prove it out. If you have an adult 50% het albino and breed it to an albino and get albinos then that means that snake is no longer 50% het. It has been proven to actually be het for albino, therefore making it 100% het for albino.

If you breed a Het Albino to a normal you will get normal looking offsprings considered 50% Het Albino. (NO albino)

To hatch an albino you need to breed a 100% Het Albino to another 100% Het Albino this would give you 25% chances per egg to hatch an albino.

100% het means the seller/breeder of that animal is absolutely positive the animal carries the gene it is het for. This means one of it's parents is a visual of the morph. A visual pied bred to any other morph or a normal will not produce ANY visual pied babies. BUT all of it's offspring will be 100% het pied. They will all carry the pied gene.

When you breed a het animal to another het animal is when you get in to 66% and 50% hets and so forth. A 100% het albino bred to another 100% het albino is a good example. Statistically out of 4 babies you will get 1 visual albino, 1 non het completely normal baby and 2 het carrying babies. The problem is, you cannot visually tell the hets from the non het, so you call the babies who are not visual from that pairing 66% het. This means 2 of the 3 are het, but until they are bred to another albino animal, you can't say which ones are.

Same basic principal with 50% hets. If you bred a 100% het pied to a spider for example. You would statistically get 2 spider babies, one of which would be het pied, and 2 normal babies, one of which would be het pied. But again, since you cannot visually tell the hets from the non hets, you call those offspring 50% hets. You have a 50/50 shot at any one of them being het for pied.

Did that make any sense at all ?

To make it easy, I always attach the word "possible" to anything that isn't 100%.

100% het means it definitely carries the gene. It came from breeding an actual albino to a normal or another het.

If you breed 2 100% hets, any normal looking offspring are 66% possible het (66% chance that they carry the albino gene) and must be bred to either an actual albino or a 100% het to try to prove it out. Your chances of getting an actual visual albino go up if you breed it to a visual albino.

If you breed a 100% het to a normal (not het or possible het at all) all babies are normal appearing and are considered 50% possible het. There is a 50% chance that they carry the gene. They also must be bred to an actual albino to prove wether or not they actually carry the gene. Or they can be bred to a 100% het to try that way.

Keep in mind, even when breeding 2 100% proven hets, you are not always going to get an albino in the clutch. You are much more likely to get visuals if one of the parents is an actual visual.

Thank you so much for all your help.

Another thing that helps me understand is the idea that those percentages are per egg, NOT per clutch. So a het albino to het albino breeding give each egg a 25% chance for normal, 50% chance for het albino, and 25% chance for albino. So technically if you have a 12 egg clutch EACH egg has a 25% chance of being an albino. You are NOT guranteed to get 25%(3) albinos out of the clutch. All 12 eggs could technically hatch out to be albino if youre really, really, really lucky LOL.

Someone referred me to this site and I go back to it a lot when dealing with the percentages. It helps me to actually see it in a table/graph form.

If you understand the basics of what terms like "100% het" and "50% het" mean, you'll be able to figure out stuff like this without calculators.
