Answer:

1) The alleles for homozygous brown hair will be BB.

2) The alleles for heterozygous brown hair will be Bb

3) Let's make a punnet square to check for the outcomes:

       B          b

B   BB        Bb

B    BB       Bb

4) The results from the punnet square depict that the phenotype of all the children produced will be brown hair.

5) The punnet square depicts that there will be a 50% probability of the child to carry the heterozygous genome (Bb) and there is also 50% probability for the child to carry homozygous dominant genome (BB).
