Detailed explanation-1: -Eye color, hair color, and blood type are all phenotypes. You may have a brown-eye phenotype, and your eyes will, therefore, be brown; a brown-hair phenotype and your hair will be brown, or an A blood type phenotype and your blood type will be A.

Detailed explanation-2: -Phenotype shown as brown or blue while dominant brown gene = B and recessive blue gene = b Individuals with bb have blue eyes, while individuals with BB or Bb have brown eyes.

Detailed explanation-3: -A phenotype is the observable physical and biochemical characteristics of an organism determined in large part by their genes. Examples of phenotypes include traits such as eye color, hair color, height, freckles, and length of fingers.

Detailed explanation-4: -The heterozygous genotype and the homozygous dominant genotype both will produce brown eyes, though only the heterozygous genotype can pass on the gene for blue eyes.

Detailed explanation-5: -In humans, phenotype examples include earwax type, height, blood type, eye color, freckles, and hair color.
