Here you have two characteristics to cross on Punnet square: Blood type and pigment.
They told you both parents are AB this means co-dominance of A and B, you draw the Punnett square (photo), and you'll see your offspring possibilities are 50% AB type, 25% A type, and 25% B type.
Now they told you both parents are homozygous for pigments this means Aa. When you draw the Punnett square (photo), you'll see your offspring possibilities are 50% Aa, 25% AA, and 25% aa.
75% pigmented and 25% albino.
