Final answer:
Uppercase letters are not used to represent dominant alleles.
Step-by-step explanation:
False. Uppercase letters are not used to represent dominant alleles. In genetics, dominant alleles are typically represented by uppercase letters and recessive alleles are represented by lowercase letters. For example, in the case of eye color, the dominant allele for brown eyes can be represented by the letter 'B' and the recessive allele for blue eyes can be represented by the letter 'b'.
