In a cross involving independently assorting loci, the cross BBYY x bbyy (assume "B" and "Y" are dominant to "b" and "y," respectively) will yield all dihybrid offspring. When those offpspring are crossed, the result is usually a 9:3:3:1 phenotypic ratio. But what if the locus "B" and "Y" did not sort independently (i.e., they were linked, at least partially)?

Question
In a cross involving independently assorting loci, the cross BBYY x bbyy (assume "B" and "Y" are dominant to "b" and "y," respectively) will yield all dihybrid offspring. When those offpspring are crossed, the result is usually a 9:3:3:1
But what if the locus "B" and "Y" did not sort independently (i.e., they were linked, at least partially)? It would mean "BY" and "by" are now more likely. How would this specifically affect the expected 9:3:3:1 ratio? To be more clear, which one of these numbers in the ratio (9, 3, 3, and/or 1) would be expected to decrease?
