 The man is Bb, the two brown eyed children are Bb (B from dad and b from mom) the blue eyed child is bb. B (brown) is dominant where b (blue) is recessive. In order to be blue eyed you must have gained the recessive b from both parents as B will always dominate over b, so mom is bb. Because they also had a blue eyed child, it tells you that dad is B dominant because of his brown eyes and has a b recessive in order to pass the recessive b to his blue eyed child.

The man is Bb, the 2 brown-eyed youngsters are Bb (B from father and b from mother) the blue-eyed toddler is bb. B (brown) is dominant wherein b (blue) is recessive.

In order to be blue-eyed, you ought to have received the recessive b from each mother and father as B will usually be dominant over b, so the mother is bb. Because additionally, they had a blue-eyed toddler, it tells you that dad is B dominant due to his brown eyes and has a b recessive with a view to skip the recessive b to his blue-eyed toddler.
