If brown hair is dominant over red hair, then a person who is heterozygous for brown hair will have a brown hair phenotype. Red-haired offspring with two brown-haired parents are fairly common.
Two parents with brown hair can produce a child with red hair.
Brown hair is much more dominant than red hair. This is why there are nearly 3 times as many brown haired people than there are red haired people in the world.

It depends what area you are talking about. If its in Europe then maybe blue eyes, or if its in India then probably brown eyes. In the whole world it is brown eyes.
brown eyes are dominant and are the most common eye colour half of the world has them population have them including me
heterzygous with brown leaves
B (dominant) is for brown and b (recessive) is for blue. If both parents have brown eyes, for them to have a blue-eyed child their genotypes (the combination of b's) must both be Bb, because they both need to provide a little b (to have blue eyes you must be double recessive (bb)). This is worked out using a Punnett Square. (example: https://mcglynn-bioreview4.wikispaces.com/file/view/basicpunnetsquare.jpg)
An allele that is always expressed when it is present is the dominant allele.

Brown is dominant, over half the world has brown eyes.
Brown eyes are dominant.
Brown eyes are dominant. That's why more people have brown eyes then hazel or blue or green.

Brown eyes are dominant.
Dominant - everything is dominant apart from diseases such as malaria, cystic fibrosis
If some gene is dominant it will always be more hereditary than a non-dominant gene. Like brown eyes, the brown eye gene is dominant so a couple with blue and brown eyes will have a child with brown eyes no matter what.
Yes.
It tells you that even though the parents have brown hair, they have a recessive allele for blonde hair also. And even though brown is suppose to be visually dominant, it is not the case at all. Two brown heads can make a blonde or brown, and of course even red haired child. Another way to look at it may be the parents have the following alleles for hair color: (b,b) - (b,b) in which case the dominant allele is Blonde or Brown.
