Dominant
Traits can be dominant which means they can be seen and are capable of masking a different trait.
Traits are dominant when they are expressed in a person who has only one copy of that gene which can be inherited from just one parent, and they usually occur as a result of genes situated on the autosomes (non-sex chromosomes). Dominant traits have the ability to hide or mask the traits (effects) of another allele (versions of gene). Dominant allele usually code for a functional protein and they are represented with uppercase letters.
