In genetics, dominant alleles are often represented by capital letters and recessive alleles by lower-case letters. Therefore, the allele for brown eyes can be symbolized as 'B' and the allele for blue eyes as 'b'.
In genetics, capital letters are used to represent dominant alleles, while lower-case letters are used to represent recessive alleles. Therefore, we can use 'B' as the symbol for the dominant brown eye allele and 'b' for the recessive blue eye allele. When both 'B' alleles are present (BB), or when a 'B' and a 'b' allele are present (Bb), the individual will have brown eyes, because 'B' is dominant. However, when both 'b' alleles are present (bb), the individual will have blue eyes, because the blue eye allele can only be expressed when the dominant allele is not present.
