: Can anyone explain (or theorize) as to just HOW I ended up with NON-tuxedo Sky Blue guppies from all-tuxedo lineage??
: Until someone pointed it out, I hadn't realized that this was the case. I went back through my breeding notes -- and sure enough! Definitely descended from Tuxedos.
: Any thoughts/comments?
: Thanks,

Well...
According to the inside of the CD jacket the X chromosome (female) contains the "Body colour and pattern (Tuxedo etc.)"
There is also a statement saying "The guppies that are included in AQUAZONE are not "pre-settled". You will find that some German Tuxedos may have, for instance, a patterned tail."
The previous two statements being said, I suppose it is possible that one of the females "Tuxedo" guppies off the CD did not carry (and therefore could not pass on) the Tuxedo trait.
