Draw a Punnett Square with parents that are both heterozygous, using the letter B.  Brown is the dominant trait and blue the recessive.  Write down each genotype and the phenotype along with the percents of each.  

Daily Triple:  

            B                             b

B          BB                          Bb

b           Bb                          bb

BB-25%, Bb-50%, bb-25%

Brown 75%, Blue 25%

What happens when a recessive allele is paired up with a dominant allele?

It is hidden / doesn't show up
