In mice, the factor for black fur is dominant. (B). The factor for brown fur is recessive (b). Use the punnet square to predict the fraction of offspring that will be black.

• All of the offspring will be black because they have a dominant factor

• Half will be because there are 2 chances for brown fur and 2 chances for black fur.

• Most will be brown.
