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.
One will be brown because the black fur is a dominant trait that means it is more likely to be black.
Most will be brown.
Animals are born with (a) , or characteristics that were passed down from their parents. These charactersitsics can be physical but they can also be (b) . The Austrian monk, (c) did a series of experiments in pea plants that shed light on how traits were inherited. He did this by observing the traits of the parent plants and then he (d) traits that appeared in the controlled offspring. He learned that there were two kinds of traits in many inherited characteristics: dominant traits and (e) traits.
