In my opinion,you're right on the mark about the statistical odds as they relate to somewhat unexpected percentages of expressive offspring.it may have just been a less than favorable roll of the proverbial "dice"....however,all of the commonly seen genetic traits currently known to us as hobbyists in regards to "Sayi "are in fact simple recessive.(with the exception of "red" & "yellow" respectively.) and the initial breeding would've produced offspring that were 100% het. for the Stillwater form of hypo,the 66% possible hets. come in the following generation,(from breeding two het. siblings.) all of the offspring from that breeding that are not hypos themselves,are said to have a 66% probability.(essentially 2 out of every 3 normal looking babies should be heterozygous.) I also think you are right about the variability of expression seen in hypos...no single genetic mutation works in a vacuum,when expressed,there are also a potential multitude of other genetic influences at work and sometimes several generations must be produced to understand exactly what's going on.
