66% Double Hets question

[GenePirate]

not 'DH' no...

Uh, yes.

[GenePirate]

correct, but - that would be 'mis-labeling' the animal

Of course, but it is a true statement that there would be a 66% chance that the animal was het for both traits in that hypothetical circumstance. This appears to be the only way that the seller (mentioned in the OP's post) could be telling the truth, however incomplete, about his/her 66% double hets. Breeding a DH to a DH will not get 66% DHs. This is what the OP was concerned about.

I have a question. In the breeding of DH to DH would the odds be greater than 66% that you would at least receive one of the mutations (regardless of which one it is) in the animal, or would it stay at 66%. What is the calculation to arrive at the figure.

As with any DH to DH breeding statically the odds are Very GOOD..i.e. breeding Pewter X Pewter still give's each animal that isn't a Double Homo a 66% chance of being a Het for both traits which means in something like a Pewter x Pewter breeding each egg only has a 6.25% chance at being a normal..which means there is a 93.75% chance that every animal will carry at least one copy of some Morph gene.

As with any DH to DH breeding the statically the odds are the same..i.e. breeding Pewter X Pewter still give's each animal that isn't a Double Homo a 66% chance of being a Het for both traits which means in something like a Pewter x Pewter breeding each egg only has a 6.25% chance at being a normal..which means there is a 93.75% chance that every animal will carry at least one copy of some Morph gene.

WOW bought him books and sent him to school, and he read them instead of eating them. LOL

Nobody said I still didn't eat them..just read them first.

Exactly. That would be the 66% chance that you'd have both genes in the same animal.

I think she's right on that one. Given the fact that the animal definitely carries one gene, there remains a 66% chance it carries the other too. So, there's a 66% chance that it carries both, otherwise it only carries one. I think that's the only situation in which the term '66% possible double het' could be kinda true.

I doubt sellers are gonna stop calling their possible double hets "66%" any time soon either way, regardless of how they were produced. At least the consumer can know better :-)
