genetics question

dragonzncornz Jun 18, 2010 06:33 PM

If you have a 100% het and a 50% het and breed them what would the babies be?

It depends.

If the 50% het proves out to be 100% het...then you will get visuals.
If not...then each baby has a 50% chance of being het...since you would go with the 100% het parent...since you know he is het.

Ok so someone who is selling a 100% het from parents with the Father being 100% het and the mother being 50% het is wrong. Just want to make sure before I make the mistake of buying a snake that I think is 100% het and it is not.

Correct.

The only way to have 100% hets is to breed a visual (let's say pied) to a normal.

Or...to prove out that the animal is a het...say from breeding het to het and getting visuals, or het to visual and getting visuals.

But you would think that if they were to prove the gene out then they wouldn't call the breeder a 50% het anymore. I would think you would call it a 100%

PHLdyPayne Jun 19, 2010 12:33 PM

Correct. A 50% het really is 50% Possible het. I certainly wouldn't buy offspring from such a combination (especially when stated 100% het to possible het (whether its 50%, 66% or even 99.9%) not unless a visual morph came out of the clutch (which would make the 50% possible het parent a 100% het).

Far better to buy hets from reliable breeders, or from breeders who you can see the parents and offspring. Even if two 100% hets are bred together, the normal looking offspring only have a 66% chance of being a het). Best bet is to buy hets from a visual morph parent bred with a normal. Then all offspring are automatically 100% hets.

And just a side note in case you are not completly up to speed on genetics even if someone breeds 2 snakes that are both 100% het for say Albino or Pied that kind of thing all the babies that are not a visuals when they hatch out are called 66% hets. Hope we have helped some.

Also just to clear it up a little more. The reason they are called 50%, 66% and 100% het is because those are your chances of your snake being the recessive gene carrier, but ultimately you have to breed to find out whether your 50% and 66% hets actually carry the gene. Like the one person said though, “once you prove it carries the gene that means it is 100%.” The percentages do not reflect how many babies will come out with the visual recessive trait though. You could only statistically come out with 100% albinos, pieds, clowns etc. etc. buy breeding visual recessive trait to visual recessive trait. Hope I helped some.

Yah it all makes sense. I figured as much. I was asking though because I was looking to purchase and realized at the last minute that the breeder (big name breeder too) was trying to sell a 100% het albino from parents where the father was 100% and mother was 50% and it just didn't add up. Thank you guys. I wont be purchasing them now.
