yea those so called markers are all bogus to me at this point. i bred my pied to a 100% het last year (she had markers and was sold to me as 100% het)... i was 0 for 6. i had a 98.something% chance of getting 1 pied,,, i lost...
Odds are fickle at best, I threw 8 out of 9 black pastel het albino's from black pastel X albino.
I'm not sure what the odds are for that happening but it's pretty small, I'd not count your girl out yet.
