Hi everyone,
If the goal is to produce a snake that is 100% homozygous for all the 3 recessive genes (hypo, albino, and anerythristic), then the "Snow X Ghost breeding/pairing" is an interesting way to evenutually (not right away, meaning the offsprings of the above pair) will eventually lead to the coveted snake that is visually and homozygous for all 3 genes at the same time.
Snow (homozygous albino, homozygous anery) bred with Ghost (homozygous hypo, homozygous anery) will produce the following results:
100% Homozygous anerythristic, 100% Definite Het. albino, 100% Definite Het. hypo
SO NOW, these offsprings bred in the future with each other would yield the following:
6.25% Homozygous anerythristic, no trait for hypo and albino 12.5% Homozygous anerythristic, Het. hypo, no trait for albino 6.25% Homozygous anerythristic, Homozygous hypo, no trait albino 12.5% Het. albino, Homozygous anerythristic, no trait hypo 25% Het. albino, Homozygous anerythristic, Het. hypo 12.5% Het. albino, Homozygous anerythristic, Homozygous hypo (visually a Ghost but also het for albino) 6.25% Homozygous albino, Homozygous anerythristic, no trait hypo 12.5% Homozygous albino, Homozygous anerythristic, Het. hypo (visually a Snow but also het for hypo) 6.25% Homozygous albino, Homozygous anerythristic, Homozygous hypo (This is the coveted snake that is visually showing all 3 genes)
It is interesting to note that if the anerythristic gene is involved in this particular breeding route, there is no chance of getting a hybino...but on the right course for getting a snake showing all 3 genes at the same time...and along the way, can get some ghost and snow.
Of course, there are other ways of reaching the stage of "Homozygous albino, Homozygous anerythristic, Homozygous hypo"...but however we honduran milksnakes lovers reach that point, it is exciting to say the least.
I hope I get the numbers right as I have checked and rechecked my statistical probability calculations.
Thanks and have a good one. ----- RAY
