Understand the concept of alleles: Alleles are different forms of a gene that can exist at a specific locus. They can be dominant or recessive.
Learn the representation of alleles: In genetic notation, alleles are often represented by letters. Dominant alleles are typically represented by uppercase letters, while recessive alleles are represented by lowercase letters.
Recognize the significance of lowercase letters: A lowercase letter indicates that the allele is recessive, meaning it will only express its trait if two copies are present (homozygous recessive).
Consider examples: For instance, if 'A' represents a dominant allele for a trait, 'a' would represent the recessive allele for the same trait.
Apply this knowledge: When identifying or writing genetic notation, use lowercase letters to denote recessive alleles, ensuring clarity in genetic representation.
