Definitions for "Genetic heterogeneity"
Similar phenotypes caused by mutations in more than one gene.
The production of the same or similar phenotypes (observed biochemical, physiological, and morphological characteristics of a person determined by his/her genotype) by different genetic mechanisms. There are two types: (1) allelic heterogeneity -- when different alleles at a locus can produce variable expression of a condition; and (2) locus heterogeneity -- the term used to describe disease in which mutations at different loci can produce the same disease phenotype.
Manifestation of similar or the same observable characteristics or traits (i.e., phenotype) resulting from different genetic mechanisms, such as changes (mutations) of different genes or a combination of genes.
