WebFeb 7, 2024 · Every gene has two versions, called alleles. We use capital letters for dominant alleles (A), and lowercase for recessive alleles (a). Dominant alleles are superior in terms of strength - if a dominant allele is present, the trait it carries will always be visible. Recessive alleles' features will only be visible if there are no dominant alleles. Weba genotype consisting of two different alleles of a gene for a particular trait ( Aa ). Individuals who are heterozygous for a trait are referred to as heterozygotes. See homozygous.
