Detailed explanation-1: -People with brown eyes are said to be independent, determined and self-confident. Yet, you never fail to remain humble. When people look at you, they get a sense of security and stability – you are known to be trustworthy. While you may want to act tough, your brown eyes portray how kind and sensitive you truly are.

Detailed explanation-2: -The bey2 gene has one allele for brown eyes and one for blue eyes. 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-3: -Eye colour, or more correctly iris colour, is often used as an example for teaching Mendelian genetics, with brown being dominant and blue being recessive.

Detailed explanation-4: -Incomplete dominance shows in individuals with lighter shades of brown and hazel. A golden-brown iris indicates the mixture of both eumelanin and pheomelanin (produces the yellow color), and hazel is usually a mixture of brown and green or blue and green, depending on the shade.
