• Homozygous: An organism with identical alleles (e.g., \(AA\) or \(aa\)) for a trait.
• Heterozygous: An organism with different alleles (e.g., \(Aa\)) for a trait.
• Dominant: An allele that masks the expression of another allele (e.g., \(A\) in \(Aa\)).
• Recessive: An allele whose expression is masked by a dominant allele (e.g., \(a\) in \(Aa\)).
