Dominant vs. Recessive Phenotype: Eye Color

Dominant vs. Recessive Phenotype: Eye Color

A phenotype in genetics is the expression of a genetic trait. The dominant gene is the allele that will surpass any other variant of that gene. In this instance, my dad’s brown eyes are the dominant trait over blue eyes. That is why I have brown eyes. My mom’s blue eyes are the recessive trait. This requires two copies of the gene in order to appear in the offspring. Dominant vs. Recessive phenotypes can be seen not only in eye color but also in hair color, having freckles or not, etc.
