Detailed explanation-1: -They suggested that brown eye color is always dominant over blue eye color. This would mean that two blue-eyed parents would always produce blue-eyed children, never ones with brown eyes. For most of the past 100 years, this version of eye color genetics has been taught in classrooms around the world.
Detailed explanation-2: -Geneticists represent the different versions of the eye colour gene as B for brown and b for blue (the capital letter is the dominant, the lowercase, recessive). So brown eyes are either Bb or BB and blue eyes are bb.
Detailed explanation-3: -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-4: -In humans, the allele for brown eyes (B) is dominant. The allele for blue eyes (b) is recessive.
