Definition of Dominant Trait. Before we can define exactly what a dominant trait is, we must first define and discuss many genetics terms. A gene, or unit of heredity, can have many different versions called alleles. There are often two kinds of alleles: Dominant allele: masks the effects of another allele; designated by an uppercase letter ; Recessive allele: effects are hidden by a dominant allele; designated by a lowercase letter ; Normally, individuals have two alleles for one gene: one from their mom and one from their dad.
