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: 1  Dominant allele: masks the effects of another allele; designated by an uppercase letter.
The genes for these traits are on the autosomes. Dominant does not mean prevalent, dominant traits can be rare (achondroplasia, TNR, NF1, etc.). Dominant means you need only one mutant gene to express the trait. In general, the heterozygote and homozygote for the mutation show the same phenotype.
