Hi,
no, that is not correct. Since there is either T pos or the amel gene on the same chromsome, there are two possible types of T pos animals.
First is the one that has one T pos gene on one chromosome and the amel gene on the other. Since the T pos gene is dominant over the amel gene the phenotype is T pos. Breed thisone to a normal and you will get 50% of animals with the amel gene and the other 50% will be with the T pos gene.
The second possibility is that one animal carries on both chromosomes the T pos gene. Since the amel gene and the T pos gene are at the smae locus, there can be either the amel Gene or Tpos at that place on the chromosome. The animal is from what I have heard the same phenotype as the half T pos half amel animals.
Breed this animal to an amel and you will get 100% T pos animals as the result. This happened to a few breeders.
Breed this animal to a Wildtype het for nothing animal and you will get 100% het for T pos. The amel gene is no longer present.
But again, this are just my thoughts about how this works.
I do just have animals that still carry the amel gene. It will take me a few more days to prove this out.
