Gene and Punnett C.F.U.

My alleles for eye color are Bb. This is an example of

• genotype

• phenotype

My eyes are brown. This is an example of

• Genotype

• Phenotype

Brown eyes are dominant (B). Blue eyes are recessive (b). If 2 siblings' genotypes are (BB) and (Bb), will they have the same eye color (phenotype)?

• Yes, because they have the same genotype

• Yes, because the dominant trait is always expressed

• No, because they have different genotypes

• No, because the recessive trait has to be expressed
