... A gene with one wild-type allele is monomorphic; a gene with two or more wild-type alleles is polymorphic. The vast majority of traits are determined by alleles of more than one gene. This means that most traits are multifactorial traits. A Heterogeneous Trait is one that may be caused by mutations ...
