Detailed explanation-1: -The allele for brown eyes is the most dominant allele and is always dominant over the other two alleles and the allele for green eyes is always dominant over the allele for blue eyes, which is always recessive.
Detailed explanation-2: -So all in all the answer to your question is neither! Blonde hair, brown hair, blue eyes, browns eyes … none of those traits are dominant or recessive, as they are not due to a single gene.
Detailed explanation-3: -For example, the allele for brown eyes is dominant, therefore you only need one copy of the ‘brown eye’ allele to have brown eyes (although, with two copies you will still have brown eyes).
Detailed explanation-4: -The allele genes come in the form of brown, blue, or green, with brown being dominant, followed by green, and blue being the least dominant or what is called recessive. Given this information, you can determine what eye colors are dominant in the parents.
