Guessing is the operative phrase here.
While it is quite possible to prove a cat hides the same as is shows, simply looking at the Pedigree and seeing both parents and all four grandparents show the same does not do that.
Based solely on the Pedigree stated, The odds are 3 in 4 that your guess is correct. But that means the odds are 1 in 4 that your dad hides something different than it shows.
