Question

the allele for brown eyes is dominant to the allele for blue eyes, explain?

Answer 1

Well this seems a bit to general, what do you mean? Are you asking about dominance in general and how it works or the molecular reasons why you see blue pigment instead of brown?

Answer 2

To begin, brown is dominant (Bb and BB give brown and bb gives blue)

Answer 3

its not to say no blue pigment is produced in the Bb genotype, but the Brown allele must make a pigment that washes out any blue pigment making the expressed phenotypic color Brown in the homozygous (BB) and heterozygous genotypes.

Answer 4

WIth no brown pigment to compete with, a person with bb (like myself), will only have the blue pigment expressed

Answer 5

Dominance becomes even more murky when you consider incomplete dominance or co-dominance. Remember its DNA-->RNA-->Protein, but it is not a trivial task to see how these proteins interact in a live organism.

Answer 6

Does this address your question or where you looking for something else?
