In humans, B is the allele for brown eyes and b is the allele for blue eyes. Two brothers both have brown eyes, but one of them has both the B and b alleles while the other only has B alleles. Which statement is true about the brothers?

Answer:

B is the dominate trait, and b is the recessive trait. Putting them together (Bb), would still mean that the brother would have brown eyes, since Bb means that the dominant trait is shown

bb- recessive trait (blue eyes)

Bb - dominant trait (brown eyes)

BB- dominant trait (brown eyes)

Hope this helps!
