Genetic heterogeneity Similar phenotypes caused by mutations in more than one gene. Genetic map A map showing the distances between markers in terms of the frequency of genetic recombination between them.
Genetic variation -- a phenotypic variance of a trait in a population attributed to genetic heterogeneity.

The biggest challenge in mapping the WSI locus is genetic heterogeneity and the lack of highly informative marker loci in the region.
If it is a disorder involving a single gene, include mention of any clinical variability; the mode(s) of inheritance; any genetic heterogeneity (locus and/or allelic); what is known about the gene(s) involved including the chromosomal locus/loci; ...
