FR: "In the case of that conda to normal, producing all condas, if that occurs a couple more times. I would question the genetics of the normal."

Caracal:"It is irrelevant how many eggs are in the clutch. If both parents are anacondas, the likelihood of all the babies being condas is EXACTLY the same as if one was a conda and one was a normal.

This is not just 'academic'.
It is a FACT.


You are exactly correct Jonny. It doesn't matter one single bit if it's Anaconda x Anaconda or Anaconda x Normal.

Caracal: "And if it happens several more times it still leaves no reason to 'question the genetics of the normal', because it had no relevance to the outcome."

Precisely!

So what if you breed this pair over and over and consistently get all Anacondas. All that might prove is that the genes from the known Anaconda seem to be virile/dominant enough to keep producing all Anacondas, it doesn't validate the female as an Anaconda because of this outcome. You could also breed this pair and ultimately produce all Normals, it doesn't invalidate the fact that the male is an Anaconda either. The producing of all Anaconda clutches, as improbable as it is, especially on a consistent basis, is still acceptable. It is also conceivable, though also improbable, that you can breed 2 Anacondas consistently and never produce a Superconda or actually produce an entire clutch of Supercondas.

Regardless. None of the current or future results will prove anything about the female being anything but Normal unless she actually produces a Superconda from this type of pairing, her to an Anaconda. Only then would we would have to accept that she would be in fact a low expression Anaconda based on the fact that she could produce a Superconda. Everything else produced from this pairing, Anacondas and/or Normals, is inconclusive regardless of how improbable or interesting the outcomes are or what we think they should be.

The only other test, other than her producing a Superconda from an Anaconda pairing, would be to breed her to any known quantity Normal and see if she produces any Anacondas. If she does, then she would have to be considered an Anaconda. If no Anacondas are produced, then the female is obviously just a normal and nothing more.

And for the record. The only time you can expect to produce an entire clutch of Anacondas is from pairing a Superconda to a Normal which is the only time that probabilities won't factor in as it's a pure given outcome based on the fact that Anacondas are the het form of Supercondas, Superconda x Normal (AA x aa = Aa). Anything else, Superconda x Anaconda (AA x Aa = AA and Aa), Anaconda x Anaconda (Aa x Aa = AA, Aa and aa) and Anaconda x Normal (Aa x aa = Aa and aa), can and will yield various results as there are more than one phenotype that can be produced from the parental gene types.
