In genetics, traits are represented by alleles, which are different forms of a gene.
Alleles can be dominant or recessive. A dominant allele is one that expresses its trait even if only one copy is present.
To represent alleles, geneticists use letters. A dominant trait is typically represented by an uppercase letter.
For example, if 'A' represents a dominant allele for a trait, then 'a' would represent the recessive allele for the same trait.
This convention helps in understanding and predicting the inheritance patterns of traits in organisms.
