You cross a true-breeding stock of black BB. mice with skinny (SS) toes to a stock of white bb. mice with fat (ss) toes. From this, you produce an F1 generation of black mice with skinny toes (Bb, Ss)

If the single genes responsible for coat color and toe appearance do
not sort independently, then you would expect to see:
A. more than 75% of your F2 black mice with
skinny toes.
B. more than 25% of your F2 black mice with
fat toes.
