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. WebWhen a gene has different alleles in a population, it is referred to as polymorphic. The rate at which alleles occur in a population is known as the allele frequency. An allele that occurs in 30% of a population would have an allele frequency of 0.3. An allele frequency of 1.0 is a fixed allele and is considered monomorphic as it occurs in ... lametta lustigWebIf we count up how many w copies are present, we find that there are five.
