Explanation:
Detailed explanation-1: -Black hair (B) is dominant over blonde hair (b); similarly brown eyes (H) are dominant over eyes(h).
Detailed explanation-2: -A dark haired parent and a light haired parent will often have a child with a color in between. Black + Blonde = Brown!
Detailed explanation-3: -The quick answer is that it is very possible (obviously!) to get a redhead from blonde and black haired parents.
Detailed explanation-4: -So, we can say that B denotes the dominant trait and b denotes the recessive trait. As black hair are dominant over brown hair, we can assume the possible genotypes for black hair to be BB or Bb. Likewise the genotype for brown hair will be bb.
